Re: [JAVA3D] [JAVA 3D] Performance Issues and Flickering

Also if you are using a very large model you may get precision issues (many old threads on this) in which case: 1) using doubles instead of floats can help 2) reducing the difference between front an back clip distance can help chris Alessandro Borges wrote: Check-list: * use a good video card (G

Re: [JAVA3D] Rasterization modes of shapes

Jasmine, you can assign a color for each vertex in you Shape3D. see: Shape3D.getGeometry() Geometry GeometryArray.setColor(); QuadArray.setColor(); TriangleArray.setColor(); (harder) You can also assign a texture with desired degradé (gradient) to each shape3D, cylinder or box. (easier) Alessandro

Re: [JAVA3D] Dual Monitor

I could ran Java3D in a GForce 2 (as primary) with a 2nd monitor attached at onBoard video card (SiS 630 - PCChips M810) and it runs Java3D demos fine, even half window in one one video and half in the other. I also could move app window from one monitor to other. I have some random crashes, but I

Check-list: * use a good video card (GForce or Radeon); * use lastest safe video drivers; * use DirectX 8.1 (if you are using Java3D D3D) ; * Use spheres with enough (not excessive) number of faces; * Use corretly the interpolators ( see SphereMotion demo as example); * Do NOT create new geometries

Re: [JAVA3D] y-up and cube env map issues

Hi Justin, I don't know if you already solve this problem, but I will give you my tips : * As Kelvin already says, the OpenGL version invert Y axis, but D3D version works fine; I guess it will be fixed soon. See my working demo at: http://www.cpm2002.hpg.ig.com.br/alessandro/cubemap/index.html Y
