Class NVBindlessMultiDrawIndirectCount

java.lang.Object

org.lwjgl.opengl.NVBindlessMultiDrawIndirectCount

public class NVBindlessMultiDrawIndirectCount
extends java.lang.Object

Native bindings to the NV_bindless_multi_draw_indirect_count extension.

This extension adds the possibility to define the number of drawcalls within a multi-draw-indirect call from the GPU, as provided by ARB_indirect_parameters, for the functions added in NV_bindless_multi_draw_indirect.

Requires NV_bindless_multi_draw_indirect, ARB_indirect_parameters.

Method Summary

Modifier and Type	Method and Description
static void	glMultiDrawArraysIndirectBindlessCountNV(int mode, java.nio.ByteBuffer indirect, long drawCount, int maxDrawCount, int stride, int vertexBufferCount) Behaves similarly to MultiDrawArraysIndirectBindlessNV, except that drawCount defines an offset (in bytes) into the buffer object bound to the PARAMETER_BUFFER_ARB binding point at which a single sizei typed value is stored, which contains the draw count.
static void	glMultiDrawElementsIndirectBindlessCountNV(int mode, int type, java.nio.ByteBuffer indirect, long drawCount, int maxDrawCount, int stride, int vertexBufferCount) Behaves similarly to MultiDrawElementsIndirectBindlessNV, except that drawCount defines an offset (in bytes) into the buffer object bound to the PARAMETER_BUFFER_ARB binding point at which a single sizei typed value is stored, which contains the draw count.

Method Detail

glMultiDrawArraysIndirectBindlessCountNV

public static void glMultiDrawArraysIndirectBindlessCountNV(int mode,
                                                            java.nio.ByteBuffer indirect,
                                                            long drawCount,
                                                            int maxDrawCount,
                                                            int stride,
                                                            int vertexBufferCount)

Behaves similarly to MultiDrawArraysIndirectBindlessNV, except that drawCount defines an offset (in bytes) into the buffer object bound to the PARAMETER_BUFFER_ARB binding point at which a single sizei typed value is stored, which contains the draw count. If the value stored at drawCount into the buffer is greater than maxDrawCount, an implementation may stop processing draws after maxDrawCount parameter sets.

Parameters:

mode - the primitive mode. One of:

POINTS	LINE_STRIP	LINE_LOOP	LINES	POLYGON	TRIANGLE_STRIP	TRIANGLE_FAN
TRIANGLES	QUAD_STRIP	QUADS	LINES_ADJACENCY	LINE_STRIP_ADJACENCY	TRIANGLES_ADJACENCY	TRIANGLE_STRIP_ADJACENCY
PATCHES

indirect - an array of DrawArraysIndirectBindlessCommandNV structures (see the extension spec for more information)

drawCount - the byte offset into the buffer object containing the draw count. This offset must be a multiple of 4

maxDrawCount - the maximum number of draws that are expected to be stored in the buffer

stride - the size of one DrawArraysIndirectBindlessCommandNV structure

vertexBufferCount - the number of vertex buffers in the DrawArraysIndirectBindlessCommandNV structure

glMultiDrawElementsIndirectBindlessCountNV

public static void glMultiDrawElementsIndirectBindlessCountNV(int mode,
                                                              int type,
                                                              java.nio.ByteBuffer indirect,
                                                              long drawCount,
                                                              int maxDrawCount,
                                                              int stride,
                                                              int vertexBufferCount)

Behaves similarly to MultiDrawElementsIndirectBindlessNV, except that drawCount defines an offset (in bytes) into the buffer object bound to the PARAMETER_BUFFER_ARB binding point at which a single sizei typed value is stored, which contains the draw count. If the value stored at drawCount into the buffer is greater than maxDrawCount, an implementation may stop processing draws after maxDrawCount parameter sets.

PATCHES

type - the data type of the element indices. One of:

UNSIGNED_BYTE

UNSIGNED_SHORT

UNSIGNED_INT

indirect - an array of DrawElementsIndirectBindlessCommandNV structures (see the extension spec for more information)

drawCount - the byte offset into the buffer object containing the draw count. This offset must be a multiple of 4
