Indeed, the best way to learn is in the GLSL shader tutorials

if 2 meshes collided returns true: bool nGetMeshesCollide(IAnimatedMeshSceneNode* mesh1,IAnimatedMeshSceneNode* mesh2) { return mesh1->getTransformedBoundingBox().intersectsWithBox(mesh2->getTransformedBoundingBox()); } here, an animator between 2 animated meshes, (the cube is the mesh, the hero is ...

don't you pass "extents" and "objDim" to vertex program? services->setVertexShaderConstant("extents", reinterpret_cast<irr::f32*>(&extents),2); services->setVertexShaderConstant("objDim", reinterpret_cast<irr::f32*>(&objDim),2); In your code seems to b...

morphing animation


or, the simplest way:

a mesh cube and a mesh oval very thin at the begin;

in the main loop scale your mesh cube to smaller dimensions and scale your oval on x and z direction to greater dimensions

a good example with HLSL here:

and here a cool example in HLSL:

take a look at this example with GLSL shader:

and search for Reflective environment mapping demo example in the list, there is a zip file free to download;

see EMaterialTypes.h in include SDK of Irrlicht:

//! Look like a reflection of the environment around it.
/** To make this possible, a texture called 'sphere map' is
used, which must be set as the first texture. */
EMT_SPHERE_MAP,

the texture is obtained from a render target texture;

when you load the mesh gun, it is loaded at 0,0,0 coordinates, then create a billboard , position it in front of the gun, then bind the billboard as child to the mesh gun;
then, all the times you move the gun, the billboard will keep relative position to the gun;

1st, render to target without water;
2nd, render with water, but change the inner pixels with the same pixels saved at the 1st pass in the render target;

make the wheels as separate meshes (separated 3D models) and then make them as children of the vehicle mesh.

if (angle==90) { angle=90.01; } something like that....., depends of the sens of rotation... or try this: if(r.Y == 0.0f) { r.Y = 0.001f; } if(r.Y == 180.0f) { r.Y = 180.001f; } ohh, no, at very small angular steps, it happened; try to work with angular step greater or equal with 1.0f (>=1.0f)

I found this "irrAn8Loader", a loader from Anim8or3D:
