WebOur goal was to explore signed distance field raymarching, and to showcase a few of its benefits related to performance, flexibility, and compositionality. We wanted to replicate the features of the raytracer in assignment 3 at closer to real-time rendering speeds. We wanted to showcase the flexibility of signed distance fields by creating Web$\begingroup$ You could try to create a signed distance field from the height map. Thats basically a 3d texture that stores the distance to the next surface. This allows to "travel the ray faster". Unreal Engine 4 uses this for mid-range ambient occlusion, soft shadows and terrain shadows in general $\endgroup$ –

WebOct 21, 2024 · The primary challenge in all path tracing techniques is how to model the scene and compute ray object intersections. In the ray marching method, an object surface is represented by a signed distance field, or SDF. The SDF is a function that when given a point returns a scalar distance indicating how close that point is to a surface.

In traditional rendering pipeline, we just post preset vertices to gpu and get what shape we want. However, these triangles seem to be sharp and cold. When we want to draw a sphere, we need to create enough triangles to hide their sharp.
