In Java3D programs, the first rendering happens only after the a resize/expose venet under JDK1.4. java -version shows the following

himalaya% java -version
java version "1.4.0-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta-b52)
Java HotSpot(TM) Client VM (build 1.4beta-B52, mixed mode)



The programs work fine under 1.3

To reproduce, please install the following:
/net/java3d.eng/export/java3d.eng/builds/release/external/1.2.1/java3d-1_2_1-fcs-b03-solsparc-rt-feb_21.bin

You need to also install packages for OpenGL from

/net/impbld.eng/cteam/ogl1.2.1/fcs/sparc


You need packages SUNWglrt SUNWglrtu SUNWglsr SUNWglsrz
and if you have FFB hardware accelerator SUNWffbgl
or if you have AFB hardware accelerator SUNWafbgl

To repoduce the bug


cd /net/java3d.eng/export/java3d/builds/java3d.eng/1.2.1/daily/programs/examples/HelloUniverse

java HelloUniverse


The cube does not come up until a resize or an expose event.



chow@eng 02/27/01:
This problem seems to appear starting around jdk1.4 beta47, it was ok before
that. The problem is that paint event(ie Canvas3D.paint() is not called)
is not generated when the window is exposed the first time.
