Re: Procedural textures via a DLL or callback?

I got it from this thread: http://news.povray.org/povray.binaries.images/thread/%3C47e997a1@news.povray.org%3E/?ttop=333517&toff=800 I do remember seeing a copy of the source the last time I looked into this, but I don't have it and I think the website which hosted it has gone down. Speaking of ...

Re: Procedural textures via a DLL or callback?

I've been looking at Tungsten (and Mitsuba, too) --- it's a really nice picture. Tungsten's got a specialised heterogeneous atmospheric renderer which does Rayleigh shading; the clouds are volumetric, but it uses a height map for the source rather than a proper 3D density function. Both were designe...

Re: Procedural textures via a DLL or callback?

The two images I posted don't use geometry at all (other than the primitives used to contain the volumes being rendered). They're not rendered using triangles or meshes. They're (effectively) heterogeneous volumetric renderings based on a 3D texture, which is generated procedurally, which is why I'm...

Re: Procedural textures via a DLL or callback?

Thanks, but I think that's not quite what I asked. Povray has its own shader language, which you can use to implement procedural textures --- it's not very quick, because it's interpreted. For my own experiments I hacked in support for DLL textures in my own copy of Povray by using dlopen() to dynam...

Procedural textures via a DLL or callback?

Hello, I'm wanting to do some work with procedural objects and I'm looking at LuxCoreRender. I'm trying to render planets, and want things like procedural clouds and atmospheric effects. See http://cowlark.com/flooded-moon/ for some pictures (done with Povray). Does LuxCoreRender have the ability to...
