GL10 class has glVertexPointer method.
GLES20 does not have this method, but has glVertexAttribPointer.
Does this mean that OpenGL ES 2.0 requires a having shader for rendering vertices?
回答1:
Yes, you need to create a vertex shader to handle the transformations, and a fragment shader that assigns the final color to a fragment (using texture sampling for example). The whole fixed-function pipeline has been removed in OpenGL-ES 2.0.
