[JAVA3D] best Sun products for 3D graphics rendering

Hi all, I have a friend who is being gifted some Sun equipment for a new school lab and has asked me what he should request. Could I ask for some suggestions on what combinations of Sun workstations and graphics cards are the top of the line for 3D graphics rendering and computation speed in gene

[JAVA3D] Alpha Manipulation

[JAVA3D] What does this EXCEPTION_ACCESS_VIOLATION mean ?

Hi I am using J2SDK1.4.0-Beta3 with Java3D 1.3.0 on a Win98 m/c. I get the error log attached below everytime I try to resize my app. by dragging the lower right corner of the app. This happens *ONLY* with Java3D apps. - not with any of the other Java apps. w/ or w/o Swing. My canvas3D is nested

Re: [JAVA3D] Memory consumption by textures

Ewan, You decompressed a JPEG and it only doubled in size? I'd expect more like a factor of ten. A typical JPG 640x480 texture will use over 1 Meg internally (for a single copy) but these commonly would be compressed (JPEG) to under 100K on disk. As noted before if you use TextureLoader you pr

Re: [JAVA3D] 3D Studio

For exporting non-animated geometry we use the ASE format with our own loader. It is an easily parsable file format. The Starfire 3DS loader is quite good for loading objects also from 3DMAX. If you want to use animation then probably the VRML format and the new Xj3D is the way to go. Dave Yaz

Re: [JAVA3D] Bug: Quat vs AxisAngle

Hi Raffi, In the implementation of AxisAngle set(Quad) and setRotation(AxisAngle) we explicitly change the magnitude to avoid divide by zero happen when computing axis. I think it is this that adjust the data back to normal somehow. But for setRotation(Quad) it just use the well known formula

Dear Dr. Michael, I recommend you the Java3D Api Specification, you can find it in http://java.sun.com/products/java-media/3D/releases.html#spec_1_3 It is better than the Api Tutorial. Im sure you will clarify main concepts. Maybe you have gotten it already. I don't know. I tell you because I

Re: [JAVA3D] Alpha Manipulation

I don't know how to make the point 1, but You must think a thing, you are using a rotPosPathInterpolator, so reversing Alpha will cause what? rotating the opposite, maybe!! I will consider the posibility of changing (reversing) the path in runtime. I hope someone give us better solutions. Regar

Re: [JAVA3D] lets port j3d to mac osX

Title: RE: [JAVA3D] lets port j3d to mac osX Hi Ian, To the best of my knowledge - Apple has an effort underway to perform a port to OSX. If Apple fails to provide a port, however, we will still need to work with Sun to get the required code and legal stuff out of the way to perform a port.

[JAVA3D] PickCanvas.pickClosest bug

Hi everyone, I think I posted this bug some time ago, but thought I'd give it a whirl with the newest release. I find that using PickCanvas.pickClosest does not always return the result nearest the user. Usually if the point is wrong, it's on the surface furthest from the viewplatform along th
