Re: [JAVA3D] Animation problem

Thank for your help~ I had found found the way to solve this problem. It is to use a Behavior which wakes up by WakeupOnElapsedFrames( 0 ) and I could do something in processStimulus() per frame. Thanks again~   Greg - Original Message - From: Pasi Paasiala To: [EMAIL PROT

[JAVA3D] Statistics on J3D Performance

Title: Statistics on J3D Performance Hi folks, I’m currently evaluating j3d performance and I would like to learn about your experiences with the j3d. I am particularly interested in identifying bottle necks, particularly in the area of collaborative environments, I/O devices, and networking.

[JAVA3D] Behaviour bounds and collision detection

Hi there, I'm having a problem with the execution of a behaviour based on collision detection. Two objects collide in my scene and a switch takes place on one object and writes to a switch for the other object. I have attached a BoundingLeaf to each object. These bounding leaves take parameters fro

hi all, i want to access to the parent of a java3d object (which is a TransformGroup) during the run time. i checked the list. it has been advised to use ALLOW_PARENT_READ. But I cannot find the definition of this under any of the classes. how can i access to the parent of a shape3d during the ru

Hi Nikolai, Thanks for the suggestion. It works this way, however, i wanted to know whether the change in functionality is due to a bug fix in Java3d 1.3 or due to some other reason? Thanks and regards, Raghav Nikolai V. Chr. wrote: Raghavendra R wrote: Hi, I have a BranchGroup in my applic

[JAVA3D] fog density

Hello, Actually I got a problem with the fog density in java3d. the fog density is changing in correlation to the size of the rendered image. if i maximize or minimize the picture with the fog, the fog is changing its density. so I like to ask u how I can solve this problem and why there is a depe

Hi Justin, thanks for your reply. In the meantime I managed to locate the landscape inside my 3D-Scene. However, I still have many problems and questions. You suggested that my test data set is fairly small, so I am now trying to work with a larger dataset with the dimensions 156*156. I can load t

Re: [JAVA3D] help needed urgetly

Ya right, I can't find no ALLOW_PARENT_READ either. I'm knew to Java3D (first post). Now I'm not the smartest man, but you probably have that TransformGroup object as the child of a BranchGroup right? So why not try setting the BranchGroup ALLOW_CHILDREN_READ capability. Then will TransformGrou
