Raymarching Shader Preview

Tool for previewing a 3d raymarching shader.

Building

Install SFML 2.5.1 to C:\SFML-2.5.1\ (or install it somewhere else and then edit line 3 of the Makefile accordingly). Then run make release.

Using

Example usage:

.\main-release.exe mucube.glsl

Here, mucube.glsl can be replaced by the filename of any shader written in GLSL 1.30 that implements a function vec3 rayColor(vec3 position, vec3 direction). The function should take as input the starting position and (normalized) direction of a ray in three-dimensional space, and return the color of a scene along that ray. You may use the uniform float time in the shader to get the time in seconds since the application was started. See mucube.glsl or moving_cubes.glsl for examples.

Use

.\main-release.exe --help

to get a list of allowed command line arguments. You can use these to start the program with a different window size, frame rate, field of view, mouse sensitivity, or camera movement speed.

You can use the mouse and WASD keys to change your view of the scene. Use F12 to take a screenshot.
