Why doesn't this work

OpenGL OpenGL: Basic Coding

I’m working on a Geforce 3 with various drivers and this is frustrating me. For some reason writemask makes vertex array not work:

glEnable (GL_DEPTH_WRITEMASK);
glEnableClientState(GL_VERTEX_ARRAY);
GLenum err = glGetError();
//err == 0x500

Hi !

0x500 is GL_INVALID_ENUM, a wild guess is that your driver does not support GL_DEPTH_WRITEMASK or something like that.

To enable writing into the depth buffer call glDepthMask(true). If you want to know if it is on or off call glGet with argument GL_DEPTH_WRITEMASK.

edit: And don’t forget to call glEnable(GL_DEPTH_TEST)
