It receives the location of the voxel as its only parameter.The Book of Shaders is a good beginners guide to the shader language.Įach shader has a map function which is executed once per voxel: Shader files are written in OpenGL Shader Language (GLSL), version 1.10. Changing MagicaVoxel's default shader directory.Determine if the provided color is one of the selected colors.Using the voxel function beyond the volume size.Functions must be declared before they are used.For my purposes (and opinion haha), it looks good enough to convey roundedness. On the comment about the first pic just using a brighter edge, that's actually my desired effect. Did you have in mind a way to go about this? (I am not tied down to my current setup for mesh/texture generation, just that it all needs to come from data instead of an obj and texture files) Even then, I will run into an issue of my UV mapping for handling colors conflicting with what my UV mapping for handling normals. That being said, I can't quite think of a way to use a normal map texture to achieve the effect - I imagine I would need a normal map for each possible face of a cube, similar to the pic below but with more cases than the 9 shown. That setup doesn't need to stay the same, but the procedural generation part will. I would opt for a normal map under normal (pun intended) circumstances, but the meshes I am working with to achieve this effect are all procedurally generated with data like 'there is a voxel at x,y,z with color a.' My current setup also includes a texture that is generated that has a pixel for each color contained in the set of voxels, and each face UV maps to that pixel on the texture.

Code is also greatly appreciated! Thanks a bunch.Ĭlick to expand.Thanks for the response, I really just need guidance on all of the terms and concepts that are all involved in this specific effect and how they are used so that I can begin to make progress. I believe this also involves using a normal map of the camera's view to detect the edges?

The darkening effect on the inner edges (blue arrow) would normally make me think SSAO or some other ambient occlusion, but the fact that it looks so similar to the outer edges but in a darker tone makes me think it is also part of this effect. This part is my knowledge so far (which may be wrong): The lightening effect (green arrow) on the outer edges appears to be an effect on the entire screen and not a specific material because it will lessen as the camera gets closer to the edges. Another set of examples are some of the pictures in this thread ( ) from Trove.īeing new to shaders and image effects, I only have tidbits of information that others have shared on how this effect might be achieved, but I don't think I know enough to write the shader/image effects needed to make those things happen. The picture is of an 'edge smoothing' effect that makes the voxels look like they are slightly rounded. I'd like to create an effect similar to the one seen in the picture below.

Hi there, in advance I'd like to share that I'm pretty new to shaders but have a gist of the basic concepts, so bear with me as I try to sound like I know what I'm talking about here.
