What can cause glDrawArrays to generate a GL_INVALID_OPERATION error?
问题 I've been attempting to write a two-pass GPU implementation of the Marching Cubes algorithm, similar to the one detailed in the first chapter of GPU Gems 3, using OpenGL and GLSL. However, the call to glDrawArrays in my first pass consistently fails with a GL_INVALID_OPERATION . I've looked up all the documentation I can find, and found these conditions under which glDrawArrays can throw that error: GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled
