Irrlicht Engine

Sorry my english.

I´m converting a DirectX program to irrlicht.
Directx has a function to projects a vector from object space into screen space: D3DXVec3Project.
How to implement D3DXVec3Project into irrlicht?

What do you need it for?

You could do it by creating a transformation matrix. You can get the current transformations with Driver->getTransform().

Here's an example

Code: Select all

matrix4 Mat;
Mat=Driver->getTransform(ETS_WORLD)*Driver->getTransform(ETS_VIEW)*Driver->getTransform(ETS_PROJECTION);
vector3df TheVector(1,1,1);
Mat.transformVect(TheVector);

TheVector should in the end hold a transformed screen space vector.
