Re: Simple Cube w/Texture

>> i assume it's there, but just to make sure, there is an onenterframe in your code to render the scene?

No – you have to animate the scene /  refresh frames in order for it to render?  I’m new to Papervision, so I’m unfamiliar with these kinds of requirements.  I know how to create onEnterFrame events of course, but what needs to animate/refresh and how in the Papervision library?

Thanks Javier – that explains a lot more.  However, I tried your code out, and while I didn’t get any errors, I didn’t see any cube either (whereas I did when I made an added a simple plane in the same file).  The .jpg (my file is city.jpg, and I changed that in your code) is in the same folder location as the host HTML and .swf.  I get this message:

 

“INFO: BitmapFileMaterial: Loading bitmap from city.jpg”

 

Here is all my code (a few things are irrelevant since I was messing around with some other things):

 

package

                        {

                                    viewport = new Viewport3D(550, 400, false, true);

                                    addChild(viewport);

 

                                    //instantiates a Scene3D instance

                                    scene = new Scene3D();

 

                                    //instantiates a Camera3D instance

                                    camera = new Camera3D();

 

                                    //renderer draws the scene to the stage

                                    renderer = new BasicRenderEngine();

 

                                    var wireframeMaterial:WireframeMaterial = new WireframeMaterial(0x333333);

                                    wireframeMaterial.doubleSided = true;

 

                                    var bitmapFileMaterial:BitmapFileMaterial = new BitmapFileMaterial("city.jpg");

                                    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");

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.
