I've been trying to writer a height map loader, the data on the GPU side appear to be fine. but when I render with GL_POINTS, I only get one pixel in the center of the screen. GL_TRIANGLE_STRIP doesn't show anything.
Here's a folder containing pictures of the callstack, vertex data, shaders, element data and the result on screen.
The only difference is I've since removed the projection and model matrix to reduce the scope of the problem.
