[JAVA3D] Fog and InfluencingBounds

2003-12-09 Thread Michael Pfeiffer
Hello, I asked a similar question yesterday and hopefully somebody has an answer for this ohne here. The class Fog knows a method setInfluencingBounds() and it requires a Bounds-Objekt to let the Fog work. But the size of these Bounds seems to be ignored, it works too if I set a BoundingSphere wit

[JAVA3D] Translating after rotating? - Local Coords

2003-12-09 Thread Ben Logan
Could someone take a quick look at the following class. The problem is that when a rotation is performed and then a translation the translation takes place on the local coordinates. i.e it moves the shape in the direction of the rotation. I want the shape to be moved in the same direction whatever

The easiest way would be to use two transformations. The first one performs only the translation and the second one, which is a child of the first, the rotation. On Tue, 9 Dec 2003 13:34:48 -, Ben Logan <[EMAIL PROTECTED]> wrote: Could someone take a quick look at the following class. The probl

Try by inverting the matrix multiplication. Let say you've got the matric M for the scene, and T for the transform. If you do M=M*T then the transform will be in local coordinatyes. If you do M=T*M then you have the transform in global coordinates... JR Ben Logan wrote: Could someone take a

hi, I am sorry if I miss the point, but I use the following transform3d multiplication to get the compound tranformation: cpTransform = translate * refptInv * scale * rotation * refPT where * refptInv is the inverse translation of refPT; * refPT is the tuple3f coordinates of center of rotation -

What you do is correct (as far as I know) cos you do something like M'=P-1*M*P where P is the passage matrix from the global base to the translated base. Hence you express the correct matrix in the global base... Another way of doing it is to reinit the matrix to ID, but having previously store
