Ray Tracing with Numpy and Autograd | Frolian's blog

Ray tracing is a tool used in many physics discipline since high frequency waves can accurately be approximated by rays. Typical applications include 3D rendering (think povray), lens design or acoustic wave simulation (which is what I do professionally).To trace rays, you usually start with a source and follow reflexions and refractions until some the end of the tracing (exiting the …

Bookmark this question. Show activity on this post. I've got some code to do basic ray tracing in a map to determine if a ray is hitting a wall or not. : The size of y_coords and x_coords is generally 18x1000 (corresponding points). self.map is 800x800. def ray_trace (self, x, y, x_coords, y_coords): ray_distances = [] resolution = self ...

This is not exactly one of those cases: porting the raytracing code to numpy required significant refactoring, because the original C++ code was following one ray's route at a time. With numpy, which is efficient when rather big arrays are used, the only practical way is to compute the same operation in parallel on all rays at the same time.

numpy.trace# numpy. trace (a, offset = 0, axis1 = 0, axis2 = 1, dtype = None, out = None) [source] # Return the sum along diagonals of the array. If a is 2-D, the sum along its diagonal with the given offset is returned, i.e., the sum of elements a[i,i+offset] for all i.. If a has more than two dimensions, then the axes specified by axis1 and axis2 are used to determine the 2-D sub …

It is a module with a few files, and only matplotlib and numpy as dependent modules. The module defines Ray, Matrix, MatrixGroup and ImagingPath as the main elements for tracing rays. Matrix and MatrixGroup are either one or a sequence of many matrices into which Ray will propagate. ImagingPath is also a sequence of elements, with an object at ...

Recently realtime ray tracing became a hot topic in the gaming community after various Minecraft Ray tracing videos started popping up. Of course, you need a monster of a machine to get decent framerates. ... I spent a weekend playing with various algorithms to create a simple ray tracer in Python by heavily leveraging NumPy. Wrote a toy ...
A Raytracer in Python - Part 1 - Fly, Crash, Raise Exception
https://stefanoborini.com/a-raytracer-in-python-part-1-basic-functionality/
Raytracing is a technique to produce a photorealistic image. It works by projecting rays from the observer to the scene, and coloring pixels on a viewplane for every ray that intersects an object. This mechanism resembles how vision works, although in the opposite direction. Light rays from a lamp hit objects and their reflection happens to ...
