Heightmap Terrain and Newton

[Innopeor]

Hello,
anyone has any example about a integration between "ITerrainSceneNode" and Newton collision manager?

This is the code im using for my static objects, but i didn't found any example in order to do the same with a heightmap terrain.

Code: Select all

void CreateNewtonMesh(NewtonWorld *world, IAnimatedMeshSceneNode *node)
{
	NewtonCollision *treeCollision;
	treeCollision = NewtonCreateTreeCollision(world, NULL);
	NewtonTreeCollisionBeginBuild(treeCollision);

	IMesh *mesh = node->getMesh();

	for (unsigned int i = 0; i < mesh->getMeshBufferCount(); i++)
	{
		IMeshBuffer *mb = mesh->getMeshBuffer(i);

		switch(mb->getVertexType())
		{
			case EVT_STANDARD:
				addMeshToTreeCollisionStandard(mb, treeCollision, node->getScale());
			break;

			case EVT_2TCOORDS:
				addMeshToTreeCollision2TCoords(mb, treeCollision, node->getScale());
			break;

			case EVT_TANGENTS:
				addMeshToTreeCollisionTangents(mb, treeCollision, node->getScale());
			break;

			default:
				printf("Newton error: Unknown vertex type in static mesh: %d\n",
				mb->getVertexType());
			break;
		}
	}

	NewtonTreeCollisionEndBuild(treeCollision, 1);

	NewtonBody* treeBody;
	treeBody = NewtonCreateBody(world, treeCollision);

	NewtonReleaseCollision(world, treeCollision);

	NewtonBodySetUserData(treeBody, node);
}

Hi,
you could use IrrNewt: http://irrlicht.sourceforge.net/phpBB2/ ... sc&start=0
Or, if you prefer to write it yourself, you can take a look at the source code.

Thanks for the answer,
well i'd like to avoid to using wrappers overall if no longer developed, in order to understand better how Newton works.

I still looking for a example without results tho..

Just try the wrapper and use it as a starting point - you can never be sure that development of something will be continued.
