silhouette

Silhouette is a raytracer that renders STL files written in C.

Usage

./bin/main fileName.stl > fileName.ppm

Basicly write your STL (Non Ascii) file as the first argument and forward the output into a ppm file.

Adjusting Camera

camMatrix variable is responsible for camera placement and direction. Depending on the size of the model, camera needs to be readjusted.

camMatrix = lookAt((V3f){100,100,150},(V3f){0,0,0});
//                     ^ Camera Origin,    ^ Target

Some Renders

Colored based on the angle between the ray and the triangle normal -- An angle shader

Also angle shader but colored uniquely per axis

Rendered with an experimental depth shader that resets every x mm
