#5080463 Boat physics engine?

Posted by Glatzemann on 25 July 2013 - 09:19 AM

Vector Unit used Bullet Physics to create Hydro Thunder Hurricane. There's a post mortem available at gamasutra: http://www.gamasutra.com/view/feature/6184/postmortem_vector_units_hydro_.php

Maybe you'll find something helpfull in there or in the Bullet forums.


#5060024 DirectXMath / DirectXCollision BoundingFrustum

Posted by Glatzemann on 07 May 2013 - 08:32 AM

I think I've solved the problem myself. The working one is the following:
using namespace DirectX;
BoundingFrustum tmp( XMLoadFloat4x4A(&proj) );
XMVECTOR det;
tmp.Transform(frustum, XMMatrixInverse( &det, XMLoadFloat4x4A(&view) ) );
I had to use the INVERSE view matrix for transformation...
