Hi all, Is there any way to get lighter the cpu percentage of a rotation? Suppose having a rotating sphere, maybe better a very slow rotation, so is there any way to stop rotation thread to free my CPU and then restart it after other tasks? Alpha is very very heavy!!! =

Hello all, I have spent some time (actually quite some time) with com.sun.j3d.loaders.vrml97.impl.Extrusion. The original version created strange results. These were mainly caused by setting up the SCP's incorrectly. In short I have made the following corrections: z[i].cross(u,v); // was pr

Re: [JAVA3D] How to keep the user at a distance???

Either collision detection or picking. Picking, if wisely implemented, WILL work much faster than current collision detection, with MUCH more flexibility, with DOUBLE-MUCH accuracy. I did use built-in collision detection, and can say that u'd have a lot of problems (resolvable though) in the futur

Re: [JAVA3D] Adding a collision detector

Just a wild guess, nothing more: make sure that in collision detector u attach _absolutely nothing_ to the scene, nothing that could stand between view point and the scene. U could also possibly be positioned inside the VRML model somehow, so that all u see is the 'blackness' inside it. I can say

Well... To make a long story short, picking means the ability to 'pick' objects from your 3D scene. Usually it is used to pick the objects with '2D Mouse'. But it also can be used to check 4 interceptions of pick implementations (PickRays, PickSegments) with other objects in the scene. U can attac

Re: [JAVA3D] Transformations

Use Transform3D class. There are some utility functions to do all this transformations avoiding editing 4x4 matrix directly, e.g.: - Transform3D.setTranslation(Vector3f) - Transform3D.rotX(angle) - Transfrom3D.setScale(scale) - etc. Read the documentation carefully to learn the working of each f
