List of glDrawElements() Examples

Examples of glDrawElements()

javax.media.opengl.GL.glDrawElements()
Interface to C language function:
void {@native glDrawElements}(GLenum mode, GLsizei count, GLenum type, const GLvoid * indices);
javax.media.opengl.GL2.glDrawElements()
javax.microedition.khronos.opengles.GL11.glDrawElements()
VBO version of glDrawElements. @see #glBindBuffer @see #glDrawElements(int mode,int count,int type,Buffer indices) @exception IllegalStateException if the most recent call toglBindBuffer for the GL_ELEMENT_ARRAY_BUFFER target had a buffer parameter of 0 (i.e., an index buffer is not bound). @exception ArrayIndexOutOfBoundsException if any index in thesequence of indices from offset to offset + count - 1 would result in a reference to an entry outside of the currently bound index or data (vertex, color, normal, texture coordinate array, weight, matrix index, or point size) array, where indices refers to the set of values bound to the GL_ELEMENT_ARRAY_BUFFER target.
