[Papervision3D] Simple Cube w/Texture

Thu Jul 2 07:01:11 PDT 2009

Hmmm... nobody?  This is a pretty simple problem, and I'm not sure where to start troubleshooting next...  is there a problem if the dimensions of the image being mapped to the object is larger than the surface area of the object itself?  Just trying to figure out why I'm only getting the wireframe and not the texture.  Code below.  Thanks!

OK cool - so now I see the cube mesh, and I can rotate it easily, but the texture is not mapped to it.  Can someone check the code I posted about two posts back and see if they see any problems with the way I am adding materials?  The .jpg is in the same directory.  Thanks!

	Try this out instead, it seems that you are using a cube and aren't loading the material list correctly.

	            wireframeMaterial = new WireframeMaterial(0x333333);
	            wireframeMaterial.doubleSided = true;
	            ///
	            //BitmapFileMaterial, doubleSided draws the color on both sides of the geometry normals
	            bitmapFileMaterial = new BitmapFileMaterial("AJ.png");
	            bitmapFileMaterial.doubleSided = true;
	            ///
	            var materialsList:MaterialsList = new MaterialsList(); 
	            materialsList.addMaterial(wireframeMaterial, "front"); 
	            materialsList.addMaterial(wireframeMaterial, "back"); 
	            materialsList.addMaterial(bitmapFileMaterial, "left"); 
	            materialsList.addMaterial(wireframeMaterial, "right"); 
	            materialsList.addMaterial(wireframeMaterial, "top"); 
	            materialsList.addMaterial(wireframeMaterial, "bottom"); 
	            ///
	            //cube = new Cube(MaterialList applied to object, width, depth, height, wSegments, dSegments, hSegments);
	            cube = new Cube(materialsList, 200, 200, 200, 3, 3, 3);
	            scene.addChild(cube);

	That's a quick example that loads a bitmap on a side of the cube, and renders a wireframe material on the other sides...

	Hope it helps =)

	Hey all,

	I'm new developing with Papervision3d (though not new to Flash/Flex/Actionscript) and have a really basic problem. I was able to display my first code-generated plane and rotate it, and also load a model collada file built with Swift3d.  Now I am trying to create a box with texture, but having problems.  Here is the relevant part of my code:

	(CubeTexture is a bitmap in Flash CS3 with linkage exported as class: CubeTexture and base class: flash.display.BitmapData)

	var bitmap:Bitmap = new Bitmap(new CubeTexture(0,0));

	material = new MaterialObject3D();

	material.bitmap = bitmap.bitmapData;

	materials = new MaterialsList();

	materials.addMaterial(material);

	primitive = new Cube(materials, 200, 200, 200);

	scene.addChild(primitive);

	I get this error:

	"WARNING: Required material not found in given materials list. Supported materials are: front, back, right, left, top, bottom & all."

	Any ideas what I'm doing wrong?  Thanks.
