[JAVA3D] Fw: [JAVA3D] Picking GeometryInfo Geometry

I've solved my problem using TRIAGLE_ARRAY instead of TRIANGLE_FAN_ARRAY. Is it possible that the picking on GeometryInfo doesn't work with an idexed goemetry? Thanks to Daniel Dvorak for the reply. - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, May 22,

[JAVA3D] Fw: [JAVA3D] New picking semantics in 1.2

I met the same problem with Java3D 1.2. I've solved the problem using the pickCanvas. If it can be useful, i've attached my class that allow to pick the first face that compose a dodecahedron (my dodecahedron is made using a group of shape3d where each geometry is obtained from a GeometryInfo

You should use the method Canvas3D.getImagePlateToVworld(Transform3D t) that create into the "Transform3D t" the transformation that you need to obtain the 3D coordinate. By, Mauro. - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 12, 2000 12:39 PM

[JAVA3D] Fw: [JAVA3D] Picking Geometry Info Shapes

Warning: currently the picking Utilities are not working with GeometryInfo structure in which the Geometry Type is indexed (e.g. TRIANGLE_FAN_ARRAY, TRIANGLE_STRIP_ARRAY, etc.). Try to use others simple structures. I hope this is useful for you. By Mauro. - Original Message - From:

This is the file you need: i hope that its format is clear enought . By, Mauro. Hi I need the geometry of the regular object dodecahedron (12 faces). I have the tetrahedron, icosahedron e octahedron. Where do I get the file with this geometry? Thanks []s Haroldo

[JAVA3D] Fw: [JAVA3D] Exact picking

I've solved this problem using a NOT INDEXED Geometry (Using an TRINAGLE_FAN Geometry i'had the same problem). "Not Picking an Indexed Geometry" is an Official Bug of Java 3D that will be solved in the next release. Good Luck, Mauro. - Original Message - From: [EMAIL PROTECTED]
