Hello mr. Bergel, I actually have done something really simple. On the construction of a cube shape in WDGeometryBuilder I simply made a method looking as follows: WDGeometryBuilder>>#addCubeWithWidth: height: depth: rotatedBy: . In the method I simply use the angle to compute the rotation when creating every single triangle (rotating every point of such triangle with respect to the y axis). It would work smoothly if only few shapes would have been instantiated but unfortunately this results in a severe drop of performance since a new shape is created for every instance of an object (because the angle rotation is different for each shape). If you still want the code I wrote for such rotation I can provide it to you, but probably that's not how proper rotations should be performed in woden.
Hopefully we can find a better solution that doesn't influence performance in such way. Cheers, Nicolas P.S. I apologize for the misleading subject of the mail. I am not using Roassal3d but I am using a package called Woden-Roassal, which works almost exactly like Roassal3d (in fact I guess they are related somehow), that is in the Woden project as default. A more appropriate e-mail subject would have been: Woden-Roassal (3d object rotations).

I should be able to hook your rotation into roassal. Can you provide your fix for the rotation please?

Now if I would like to rotate objects it wouldn't be too bad if I were using Woden at his "lowest layer" but I am actually building cubes with Woden-Roassal and there I get lost. I already made some rotations on Woden built arbitrary objects, now I would like to extend it to objects built from Woden-Roassal but I honestly miss on finding the connection between the two. I saw that the base shape is built in: RWCube>>#createBaseShapeNode, I would be able to build a rotated shape from there but that would result in all shapes being rotated in such way since in RWSimpleShape>>#buildRenderableFor:view: when we select the shape: baseShape := aView baseShapeNodeNamed: self baseShapeName ifAbsentPut: [ self createBaseShapeNode ]. we would get back the previous base shape defined. Any suggestions on how to do it? Cheers, Nicolas
