OpenGL Issue

andreaArc

Hi, I have a problem with the 3D graphichs. If I run this sketch:

void setup()
{
  size(100,100,P3D);

}

void draw()
{

}

Processing does not show anything and I get this error:

OpenGL error 1285 at bot beginDraw(): out of memory OpenGL error 1286 at bot beginDraw(): invalid framebuffer operation

I am working with Processing 2.2.1 - winXp 32bit sys - GCard NVida GeForce Go 7400 with the latest updated driver.

How can I fix this?

ps 1.5.1 does not work on my machine anymore, it does not even start (Launch4j "An error occurred while starting the application").

many thanks!

...and if I try running it in Eclipse i get:

Select code and hit Ctrl+K (or use the C button) to format code and stack traces.

For Eclipse, take a look at http://wiki.processing.org/w/How_I_can_make_a_sketch_with_libraries_in_Eclipse? But I am not sure if result will change from PDE.

I can run 2d sketch from eclipse but not 3d. Same in processing.

Chrisir

please don't try an empty code, but a longer sketch

does size(100,100,P3D); and size(500,400,OPENGL); make any difference?

Did you in processing IDE preferences (ctrl and comma or via menu) increase the memory?

;-)

andreaArc

I ran the directional ligth example - no change I tryed with both sizes - no change I have increased the memory - no change :( Thanks!

In Processing 2, PD3 = OPENGL! :-B

@GoToLoop I have heard that too, so are they exactly the same?? If so, why not just get rid of one of them?

GoToLoop

Processing 1 had P3D & OPENGL as unique renderers.
While in P3D, the 3D was emulated, OPENGL was the real deal.
For a better transition to Processing 2, they left P3D available, even though it's now the same as OPENGL!

println(P3D == OPENGL);
println(isGL());

mcspud

@GoToLoop ok, thanks

But JAVA2D is still different from P2D, right? Or does P2D = OPENGL?

GoToLoop

JAVA2D is the only renderer that was kept intact from Processing 1!
Even OPENGL was upgraded for a more updated version!

Original P2D & P3D renderers were cut off in Processing 2.
P3D became synonym for OPENGL and P2D is an emulated 2D using OPENGL!
