Shaders

I am interested in the power of math and code to create beautiful visual effects, so I enjoy experimenting with shaders. I have used node based editors but also feel comfortable using ShaderLab and HLSL to write custom shaders. Take a look at a few of my shader experiments below!

This is a work in progress shader tutorial. Hopefully it will give you an idea how how I think about shader development!

(and convey my enthusiasm for learning and experimentation)

Stencil Shader

This visual effect consist of
"panes" that write to the stencil buffer and custom object textures that read from the stencil buffer and so that objects and materials appear differently depending on which side of the cube the player is looking through.

Additionally, objects are able to seamlessly switch which stencil layer they are reading from without clipping from either side! This is what allows the rabbit to enter "spring" and disappear from "winter" without ever being out of sight.

Runtime Drawing Shader

This is by far the most complex shader I have worked with. It uses the mouse position on the uv texture to write to a render texture, which is then written to a dynamic runtime texture mask . This render texture is then used to know which areas of the book should render as clean, and which should remain dirty.

To evaluate the cleanliness, the game also draws the texture mask to a downsampled runtime texture. The pixel colors in this texture are used as a measure for whether the book is clean yet!

Pixelate Image Effect Shader

This pixel shader uses an image effect shader to pixelate the screen, and then samples from a palette to choose the appropriate color for a pixelated effect with a limited color palatte.
