Environment Mapping (esp. for GuiObjectView)

by Robert Nall · in Torque Game Engine · 08/02/2004 (9:39 am) · 2 replies

Hey all, I was hoping to get some direction into enabling environment mapping in the guiObjectView resource. I noticed showTSShape had some code for emaps, but I don't know enough about openGl to figure out how it's supposed to work and my copy and paste attempt at implementing the showTSShape emaps in GuiObjectView didn't work out ;) So, if anyone out there happens to know a thing or two about emapping, I'd appreciate some help with this.

Thanks,

Okay, a little more research into TSShapeInstances and I got my emaps figured out. If anyone's interested, here's what I did:

In GuiObjectView.cc near the top after the other globals I put in my emap globals:
...

static const S32 MaxAnimations = 6;

// emap additions
//change this to point to your environment map
const char * emapMatName[] = { "starter.racing/data/skies/guiView_env.jpg" };

MaterialList emapMatList(1,emapMatName);
//end emap additions

IMPLEMENT_CONOBJECT( GuiObjectView );

...

Go down to GuiObjectView::meshObjects::load() and after the skin loading code add in these three lines:
...

		materialList->mMaterials[0] = texture;
	}

    // emap additions
    emapMatList.load(MeshTexture,0,true);
    mMesh[index].mesh->setEnvironmentMap(emapMatList.getMaterial(0));
    mMesh[index].mesh->setEnvironmentMapOn(true, 2.0); // second number sets the level of emap (0 = off)
    // end of emap additions

	if (pNode == -1)

    ...

And that should be it. It turned out to be much easier than I thought. Hope someone else finds it useful ^_^
