Re: Help me implementing PS and VS shaders

[Yuri Vl. Gushchin]

Two classes from the referred post are compiling without any problems in my environment.

I use latest Xith3D sources from CVS, JDK 1.4.2_01 and ANT 1.5.4.

If you still have problems, I can help you to resolve it step-be-step.

Maybe classpath during the compilation is not what you expect it to be.

[Yuri Vl. Gushchin]

JCD, please check if you have Xith3D installed in your JDK's lib/ext (both JDK and JRE), check that you don't have CLASSPATH variable set, and JAVA_HOME points to valid JDK home...

...well, anyway, the same basic instructions...

JCD, do you use plain javac or ant build script (build.xml)? Please use ant script - it should work just fine.

I sometimes have similar, incidental & strange, compilation errors but in my JBuilder environment.
Exiting JBuilder, then deleting the project's classes directory, and forcing a complete recompile has always
solved these errors for me.

OK, I will check this out, but I'll be able to do this nearest in a week...

Party time
I "think" I got them pixel and vertex shaders to work, lemmie see if I can make a little demo
PS:
This is how I declare them
appearance.setShaderProgram(new VertexShader(string, prarmeters));
appearance.setShaderProgram(new FragmentShader(string, prarmeters));

[Java Cool Dude]

Damn, it works for few seconds with the right effect and then everything disappeared at once
You can find all the classes that I created/modified here
We're almost there folks :p

[Java Cool Dude]

Actually the first frame works just fine,  and then the geometry disapears...

[Java Cool Dude]

Ummm now I can see a flaw in the way I implemented PS and VS:
There could be only one program at once....doh
I need to create a ShaderProgramUnitState where I can have PS and VS shaders combined.
Tell me what you guys think, after all I'm not doing it for my sake alone

I see the secret behind disappearing object:
In ShaderProgramPeer, doneShading function is only called once during the entire program.
I checked TetureShaderPeer and it was in fact calling that same method all the time...
Hmmm back troublesooting

[Java Cool Dude]

Man, only one thing to do and then w00 w00:
Getting doneShading in ShaderProgramPeer to be called more than once during runtime

[Java Cool Dude]

W00h00 I got them fully working in Xith3D now yay.
/me off making a demo.
PS: I thought the good news deserved a new thread

Please delete this thread

dont- its good to see a mind at work history in the making  

[Yuri Vl. Gushchin]

There will be (I hope) a time when we will create more detailed developer's guide on how internals of Xith3D work.
