Making Faster Fragment Shaders by Using Tessellation Shaders
Demonstration of how we can use tessellation shaders to make faster fragment shaders.
You can read the details in my blog
GUI Usage
I will describe how to use the GUI.
-
Wireframecheck this checkbox to render the teapot in wireframe. -
Do Vertex Calculationcheck this checkbox to move the calculation(either specular lighting calculation or procedural texture calculation) from the fragment shader to the vertex shader -
Use Tessellationif checked, the calculation is moved from the fragment shader to the tessellation evaluation shader. -
TessLevelcontrols the tessellation level of the tessellation shader. -
Render Modecontrols whether we are calculating specular lighting, or we are calculating a procedural texture on the teapot.
Building
If on Linux or OS X, you can build it in the terminal by doing:
mkdir build && cmake .. && make
you can then launch the app by using the launch script:
./launch-tess_opt.sh
If on Windows, create a build/ folder, and run cmake .. from
inside that folder. This will create a visual studio solution(if you
have visual studio). Launch that solution, and then choose to compile the
project named tess_opt.
