You can't do it with a rotation matrix. You need a translation matrix to move vecCentral to the origin, then a rotation matrix to rotate the world, then the inverse of the translation matrix to move the origin to vecCentral. I'd be trying to find m.translate() and m.rotate() in the matrix class. Pe...

huh, I guess I'll have to note that down. Although the normal values should be correct - in that they're all -1, 0, or 1. In any case it hardly matters, I'm going for that accurate 80's vibe so no lights :P If you aren't doing lighting then it doesn't matter. :) But in case you later decide to use ...

                    //These windings should be correct, I'm not sure what Nx, Ny, Nz do so I copied them from known good code, and set them to 1 (this code uses increments of 1, the other code uses increments of 2 and has them set to 2                     video::S3DVertex(x-0  ,  1  ,  y+0, -1, 1,-...

If you need a simple algorithm for turning concave polygons into triangles, have a look at Ear Clipping: http://www.geometrictools.com/Documentation/TriangulationByEarClipping.pdf Although be careful searching youtube or google image search for it, you'll get videos/pics of dogs having their ears cr...

No, you were right. Cone Step is just another alternative that not many people use. I've never heard of a game using CSM (due to previous patent issues I'd guess) but a ton use Parallax Offset / Steep Parallax / Relief mapping. Normal mapping distorts the surface normal to affect lighting. Parallax ...

It's put in the BlendOperation member of the SMaterial class.
I don't actually know where to use the SMaterial though, I'm not actually an Irrlicht user.

Another interesting one is FastBuild. http://www.fastbuild.org/docs/home.html It can do automatic unity builds (not unity the game engine, I mean the c++ project organisation technique that can dramatically speed up builds), distributed network builds, etc. I've found it rather tricky to use though ...

A great resource for near/far plane values is http://www.sjbaker.org/steve/omniv/love ... uffer.html
It has a javascript calculator that lets you enter the near and far values and tells you the precision at different distances.

You could also try using subtractive blending by setting the blend operation to EBO_SUBTRACT. The same kind of texture as in additive (black areas have no effect) will now get darker as more of them overlap, giving a dark smoke. (Modulative (multiply) and subtractive will look a bit different. Modul...

I'm only rendering 1200 cubes (each cube has 12 triangles thus 14400 triangles in total) Actually it looks like double that. Each side of the cube is being rendered with 4 triangles (two front facing, two back facing), so there's 24 triangles per cube and effectively no back face culling happening ...

I've not figured out a way around that yet unfortunately. (edit: my hope is that premake might allow for it, but I haven't found time yet to learn that) Premake does have relative paths. I've started using it for my own stuff recently. I can just go to a command prompt and type "premake5 vs201...

This CG shader is very similar to Normal Parallax Mapping with two big differences namely "Specularity" (in a primitive form) and "Self Shadowing" (also quite primitive) rendered at remarkable speed. One that I really like is Cone Step Mapping. It's like parallax occlusion mappi...

As Nvidia's own CG documentation says: NVIDIA and Microsoft collaborated to develop the Cg language. Microsoft calls its implementation High-Level Shading Language, or HLSL for short. HLSL and Cg are the same language but reflect the different names each company uses to identify the language and its...

and in a pixel shader can affect the use of 'else' ? I found this on a steep parallax shader:     Coord = (Coord + oldCoord)*0.5;     if( Height < 0.0 )     {         Coord = oldCoord;     } Is this the optimal way? Shaders make flow control (like if/else and loops) a bit trickier. A GPU has a heap...
