List of glGenBuffers() Examples

Examples of glGenBuffers()

javax.media.opengl.GL.glGenBuffers()
Entry point (through function pointer) to C language function:
void {@native glGenBuffers}(GLsizei n, GLuint * ids);
javax.media.opengl.GL2.glGenBuffers()
javax.microedition.khronos.opengles.GL11.glGenBuffers()
Generate buffer object names.
glGenBuffers returns n buffer object names in buffers.
These names are marked as used, for the purposes of glGenBuffers only, but they acquire buffer state only when they are first bound, just as if they were unused.
Errors

GL_INVALID_VALUE is generated if n is negative. @param n Specifies the number of buffer object names to be generated. @param buffers Specifies an array in which the generated bufferobject names are stored. @param offset the starting offset within thebuffers array. @exception IllegalArgumentException if buffers isnull. @exception IllegalArgumentException if offset isless than 0. @exception IllegalArgumentException ifbuffers.length - offset is less than n.
