Hello !

I've got a problem in a program using Quad Array geometries with Java 3D v 1.3 and Direct3D 8.1

I used to work on Java 1.2.1 (Direct3D) and everything worked perfectly but now I switched to 1.3 (Direct3D) and I get "Fail to create Vertex Buffer - D3DERR_INVALIDCALL" when rendering scenegraph containing this kind of code :

---
Point3f[] face=new Point3f[4];
face[0] = new Point3f(-1,-1,0);
face[1] = new Point3f(-1,1,0);
face[2] = new Point3f(1,-1,0);
face[3] = new Point3f(1,1,0);
com.sun.j3d.utils.geometry.GeometryInfo ground= new 
com.sun.j3d.utils.geometry.GeometryInfo(com.sun.j3d.utils.geometry.GeometryInfo.QUAD_ARRAY);
ground.setCoordinates(face);
Shape3D s=new Shape3D(ground.getGeometryArray());
mainTransformGroup.addChild(s);
sceneRoot.addChild(mainTransformGroup);
---
Can anyone help me ? :)

Thanks in advance

Probably the driver you got doesn't support DirectX8.0 well
which Java3D v1.3 use.
Java3D v1.2.1 use DirectX 7.0 API.

Try update the driver.
