Re: need help with per-vertex lighting

I think I will put aside this problem for now and work on something else. It's just getting ridiculous. If I could use quads, it would be so simple. The only thing I could come up with is to store all 4 vertex-colors of a square inside the primitive's provoking vertex (which I only just heard about....

Re: need help with per-vertex lighting

Ok, after reading a bit about shader attribute variables, I decided there is no way to change the way interpolation between vertices is done. So the color I get to use inside the fragment shader will always be triangle-interpolated and it's impossible to modify the weighting. For example, the right-...

Re: need help with per-vertex lighting

Your patch... Is it part of some other Irrlicht branch or how do I get it? Can you give me a quick overview about what Irrlicht versions there are? Because I only ever used the "standard" version. I think doing some fake quad interpolation on triangles inside the vertex-shader probably isn...

Re: need help with per-vertex lighting

All I ever did inside fragment shaders was to use either global or vertex-interpolated values. No idea how I'd do per-pixel lighting. I googled it, but didn't find anything enlightening... So... I would need a light map for every surface I guess? In a large voxel world that would easily make hundred...

Re: need help with per-vertex lighting

Let's assume for a moment I never said anything about quads ^^
Would you have any suggestion how I can make the transitions in the second picture look like in the first?

need help with per-vertex lighting

I use vertex colors as some kind of static lighting, so I can raycast to each vertex only when changes occured in the world and have shadows without any performance loss. I know it doesn't look very pretty, but with some smoothing later on, I think it will suit my needs. I suppose the problem is, I ...

Looking for free resources

Does anyone have good links to free texture (particularly seamless tile-like ground textures) and sound collections that may be used in a commercial project?

Re: using material values inside custom shader?

I did, but it doesn't say how I would use the material's set ambient color, for example, inside the shader.

I would set it as a constant, if I knew how to get to it...

I guess I will need to use onSetMaterial and store the material-variables inside the derived callback class.

using material values inside custom shader?

How?...

I've only used the IShaderConstantSetCallBack::OnSetConstants function so far.

Re: fading in/out skybox

I tried it again with color transparency and ambient color. I had forgotten to enable lighting, because it's usually on by default (except for skyboxes...).

Works the way I wanted now. Thanks anyway.

fading in/out skybox

I want to gradually set transparency for my skybox. Behind it there's only the scene-color. I tried to get to the vertices by casting to IMeshSceneNode, but it doesn't work. Otherwise I could have used vertex-transparency. Using color-transparency together with the material's ambient color doesn't s...

Re: Custom Material Renderer using Custom Vertices

I don't even know what it is :/

I think I might once again use a dirty workaround and use the vertex normal-components for other purposes, but in the long run, being able to define my own vertices might be handy.

Re: Custom Material Renderer using Custom Vertices

You can check how to define custom vertex type in following example: http://sourceforge.net/p/irrlicht/code/HEAD/tree/branches/shader-pipeline/examples/29.HardwareSkinning/main.cpp So, after a year I finally looked into that example, because I'm at a point now, where 2TexCoord-vertices won't do any...
