Binary that renders a triangle using Open GL, scans the resulting image to a PNG, and makes an occlusion query to determine the number of fragments shaded. To be used as reference when developing Turnip.

Open GL occlusion query demo

Overview

This repo contains the source for an applicaiton that renders triangles using Open GL, saves the output as a PNG, and outputs the number of shaded fragments via an occlusion query. This applicaiton is used as a reference for implementing occlusion queries for Vulkan on Turnip.

Instructions

Enter the CrOS chroot and set up the boards you want to test against (setup_board --board=${BOARD}).
Emerge mesa, and libpng to the device under test (emerge media-libs/mesa libpng && cros deploy ${IP_ADDR} ${PACKAGES}).
make shaders
target={local, atlas (i915), cheza (adreno)} make
