Class ARBMultiBind


  • public class ARBMultiBind
    extends java.lang.Object
    Native bindings to the ARB_multi_bind extension.

    This extension provides a new set of commands allowing applications to bind or unbind a set of objects in a single call, instead of requiring a separate call for each bind or unbind operation. Using a single command allows OpenGL implementations to amortize function call, name space lookup, and potential locking overhead over multiple bind or unbind operations. The rendering loops of graphics applications frequently switch between different states, binding different sets of resources, including texture objects, sampler objects, textures for image loads and stores, uniform buffers, and vertex buffers; this extension provides "multi-bind" entry points for all of these object types.

    Each command in this extension includes a <first> and <count> parameter, specifying a continguous range of binding points to update, as well as an array of <count> object names specifying the objects to bind. Unlike single bind commands, multi-bind commands can be used only to bind or unbind existing objects. Passing a previously unused object name (generated or not) results in an error and does not create a new object. For binding points with associated data (e.g., ranges of a buffer), separate arrays are used to pass the associated data for each binding point. Passing zero values in the array of object names removes the object bound to the current bounding point. Additionally, if NULL is passed as the array of objects, objects bound to the entire range of binding points are unbound, as though the caller passed an array of zeroes.

    Requires OpenGL 3.0. Promoted to core in OpenGL 4.4.

      • glBindBuffersRange

        public static void glBindBuffersRange​(int target,
                                              int first,
                                              @Nullable
                                              java.nio.IntBuffer buffers,
                                              @Nullable

                                              PointerBuffer sizes)
        Binds count existing buffer objects to bindings numbered first through first+count-1 in the array of buffer binding points corresponding to target. offsets and sizes specify arrays of count values indicating the range of each buffer to bind. If buffers is NULL, all bindings from first through first+count-1 are reset to their unbound (zero) state. In this case, the offsets and sizes associated with the binding points are set to default values, ignoring offsets and sizes. It is equivalent to:
        
         for ( i = 0; i < count; i++ ) {
             if ( buffers == NULL ) {
                 glBindBufferRange(target, first + i, 0, 0, 0);
             } else {
                 glBindBufferRange(target, first + i, buffers[i], offsets[i], sizes[i]);
             }
         }

        except that the single general buffer binding corresponding to target is unmodified, and that buffers will not be created if they do not exist.

        The values specified in buffers, offsets, and sizes will be checked separately for each binding point. When values for a specific binding point are invalid, the state for that binding point will be unchanged and an error will be generated. However, state for other binding points will still be changed if their corresponding values are valid.

        Parameters:
        target - the buffer object target. One of:
        ARRAY_BUFFERELEMENT_ARRAY_BUFFERPIXEL_PACK_BUFFERPIXEL_UNPACK_BUFFER
        TRANSFORM_FEEDBACK_BUFFERUNIFORM_BUFFERTEXTURE_BUFFERCOPY_READ_BUFFER
        COPY_WRITE_BUFFERDRAW_INDIRECT_BUFFERATOMIC_COUNTER_BUFFERDISPATCH_INDIRECT_BUFFER
        SHADER_STORAGE_BUFFERPARAMETER_BUFFER_ARB
        first - the first binding
        buffers - an array of names of existing buffers objects
        offsets - an array of offsets
        sizes - an array of sizes

        Unsafe version of: BindTextures
        Parameters:
        count - the number of texture objects
      • glBindTextures

        public static void glBindTextures​(int first,
                                          @Nullable
                                          java.nio.IntBuffer textures)
        Binds count existing texture objects to texture image units numbered first through first+count-1. If textures is not NULL, it specifies an array of count values, each of which must be zero or the name of an existing texture object. When an entry in textures is the name of an existing texture object, that object is bound to corresponding texture unit for the target specified when the texture object was created. When an entry in textures is zero, each of the targets enumerated at the beginning of this section is reset to its default texture for the corresponding texture image unit. If textures is NULL, each target of each affected texture image unit from first through first+count-1 is reset to its default texture.

        BindTextures is equivalent to:

        
         for ( i = 0; i < count; i++ ) {
             uint texture;
             if ( textures == NULL ) {
                 texture = 0;
             } else {
                 texture = textures[i];
             }
             ActiveTexture(TEXTURE0 + first + i);
             if ( texture != 0 ) {
                 enum target; // target of texture object textures[i]
                 BindTexture(target, textures[i]);
             } else {
                 for ( target in all supported targets ) {
                     BindTexture(target, 0);
                 }
             }
         }

        except that the active texture selector retains its original value upon completion of the command, and that textures will not be created if they do not exist.

        The values specified in textures will be checked separately for each texture image unit. When a value for a specific texture image unit is invalid, the state for that texture image unit will be unchanged and an error will be generated. However, state for other texture image units will still be changed if their corresponding values are valid.

        Parameters:
        first - the first texture objects
        textures - an array of zeros or names of existing texture objects

                                           long samplers)
        Unsafe version of: BindSamplers
        Parameters:
        count - the number of sampler objects
      • glBindSamplers

        public static void glBindSamplers​(int first,
                                          @Nullable
                                          java.nio.IntBuffer samplers)
        Binds count existing sampler objects to texture image units numbered first through first+count-1. If samplers is not NULL, it specifies an array of count values, each of which must be zero or the name of an existing sampler object. If samplers is NULL, each affected texture image unit from first through first+count-1 will be reset to have no bound sampler object.

        BindSamplers is equivalent to:

        
         for ( i = 0; i < count; i++ ) {
             if ( samplers == NULL ) {
                 glBindSampler(first + i, 0);
             } else {
                 glBindSampler(first + i, samplers[i]);
             }
         }

        The values specified in samplers will be checked separately for each texture image unit. When a value for a specific texture image unit is invalid, the state for that texture image unit will be unchanged and an error will be generated. However, state for other texture image units will still be changed if their corresponding values are valid.

        Parameters:
        first - the first sampler object
        samplers - an array of zeros or names of existing sampler objects

                                                long textures)
        Unsafe version of: BindImageTextures
        Parameters:
        count - the number of image units
      • glBindImageTextures

        public static void glBindImageTextures​(int first,
                                               @Nullable
                                               java.nio.IntBuffer textures)
        Binds count existing texture objects to image units numbered first through first+count-1. If textures is not NULL, it specifies an array of count values, each of which must be zero or the name of an existing texture object. If textures is NULL, each affected image unit from first through first+count-1 will be reset to have no bound texture object.

        When binding a non-zero texture object to an image unit, the image unit level, layered, layer, and access parameters are set to zero, TRUE, zero, and READ_WRITE, respectively. The image unit format parameter is taken from the internal format of the texture image at level zero of the texture object identified by textures. For cube map textures, the internal format of the TEXTURE_CUBE_MAP_POSITIVE_X image of level zero is used. For multisample, multisample array, buffer, and rectangle textures, the internal format of the single texture level is used.

        When unbinding a texture object from an image unit, the image unit parameters level, layered, layer, and format will be reset to their default values of zero, FALSE, 0, and R8, respectively.

        BindImageTextures is equivalent to:

        
         for ( i = 0; i < count; i++ ) {
             if ( textures == NULL || textures[i] = 0 ) {
                 glBindImageTexture(first + i, 0, 0, FALSE, 0, READ_ONLY, R8);
             } else {
                 glBindImageTexture(first + i, textures[i], 0, TRUE, 0, READ_WRITE, lookupInternalFormat(textures[i]));
             }
         }

        where lookupInternalFormat returns the internal format of the specified texture object.

        The values specified in textures will be checked separately for each image unit. When a value for a specific image unit is invalid, the state for that image unit will be unchanged and an error will be generated. However, state for other image units will still be changed if their corresponding values are valid.

        Parameters:
        first - the first image unit
        textures - an array of zeros or names of existing texture objects

        Binds count existing buffer objects to vertex buffer binding points numbered first through first+count-1. If buffers is not NULL, it specifies an array of count values, each of which must be zero or the name of an existing buffer object. offsets and strides specify arrays of count values indicating the offset of the first element and stride between elements in each buffer, respectively. If buffers is NULL, each affected vertex buffer binding point from first through first+count-1 will be reset to have no bound buffer object. In this case, the offsets and strides associated with the binding points are set to default values, ignoring offsets and strides.

        BindVertexBuffers is equivalent to:

        
         for ( i = 0; i < count; i++ ) {
             if ( buffers == NULL ) {
                 glBindVertexBuffer(first + i, 0, 0, 16);

When a value for a specific binding point is invalid, the state for that binding point will be unchanged and an error will be generated. However, state for other binding points will still be changed if their corresponding values are valid.

        Parameters:
        first - the first vertex buffer binding point
        buffers - an array of zeros or names of existing buffers objects
