Visualizes what all the sampler parameters do. Shows a textured plane at various scales (rotated, head-on, in perspective, and in vanishing perspective). The bottom-right view shows the raw contents of the 4 mipmap levels of the test texture (16x16, 8x8, 4x4, and 2x2).

Two Cubes

See it on Github!

This example shows some of the alignment requirements involved when updating and binding multiple slices of a uniform buffer. It renders two rotating cubes which have transform matrices at different offsets in a uniform buffer.
