Support / Re: setVertexOptimization
« on: June 28, 2011, 04:56:12 pm »
Thank you for your quick response!

I tried to use setShadingMode();
It's also very useful function.
But I want to make a object which has flat and smooth both type faces.
Then, next I want to try PolygonManager.

Should I use getTransformedNormal() function?
Could you tell me a example of using PolygonManager?

Support / setVertexOptimization
« on: June 27, 2011, 05:27:24 pm »
Hello,
I have a question about setVertexOptimization.


This cube is separated into 6 faces in blender.
I tried to load this cube without vertexoptimization. (setVertexOptimization(false))

In my expectation, it become like a FLAT SHADING.
Which has sharp edges.
But shading result is not.
(Maybe shading result is not change by using vertexoptimization.)

How should I use setVertexOptimization?

I found my mistake.

The cause was in my modeling data.
Sometimes my blender exports incorrect data.
Perhaps my modeling data contain some discrepancy polygons.
JPCT-AE loads other 3ds data correctly.

Thank you for your kind advices and great framework!

Thank you for your usual support.
I understood about the restriction of 3d model and the memory size.

My 3ds model is simple cube.
File size is 4kb.
Polycount is 12.
And every faces are triangle.

To make sure I tried to load other 3ds model.
But result was same.
Maybe I made a basically fatal mistake...

If possible I want refer to example project.
Do you have downloadable load3ds example project?

What is my mistake?

And I'm just trying Object3D.mergeAll...

Thank you very quick response.
And I'm sorry about my bad English and explanation.

When I try to run the program, following dialog appear.
------
!Sorry!
The application HelloWorld(process com.threed.jpct.example) has stopped unexpectedly.
Please try again
------

I tried to change the code
( thing = loadModel("res/" + thingName + ".3ds", thingScale); )
to
( thing = Primitives.getCube(15); )
It works correctly.

Maybe problem is in last function (Object3D loadModel())....

Hello,

Could you tell me that what is my mistake?
Or is there simple load3ds example for android?

Thank you.
