it's just experimental and not useful. but now i understand opengl a little bit better and can enhance this module.

ps: this will not work for android. i've no idea whats going wrong but i think i can fix that

a new version is available

changes:

01/01/2011 v0.1
added	: Color.toArray:Float[]()
added	: Color.toBuffer:Int(buffer:DataBuffer, address:Int)
added	: Color.toString:String()
added	: Vertex.toBuffer:Int(buffer:DataBuffer, address:Int)
added	: Entity.SetColor:Void(col:Color4F)
added	: Entity.SetColor:Void(col:String) can actually be white, black, red, green, blue, yellow, magenta, grey, lightgrey, darkgrey, orange or brown
added	: Entity.GetColor:Color4F()
added	: Color.New(col:Color4F)
added	: Color.New(col:String)
added	: Vector.toArray:Float[]()
added	: Light.New(number:Int = GL_LIGHT0, lightType:Int = LIGHT_DIRECTIONAL)
added	: S3D.CreateLight:Light(lightType:Int = LIGHT_DIRECTIONAL)
added	: CreateLight:Light(lightType:Int = LIGHT_DIRECTIONAL)
changed	: MeshFileFormat: the chunk "face" has now 7 values: x, y, z, r, g, b, a for a vertex, RGBA is optional
fixed	: Mesh.New(meshFile:String) not longer read indices to vertices
note	: Lights can be created but are currently ignored because there are no material functions in s3d
note	: if CreateLight() returns Null, there be more than 8 lights in your code
note	: a bug (or my fail) prevents that a mesh can have vertex colors

v0.1 Module : http://www.sedm.de/monkey/s3d/s3d.zip
v0.1 Example: http://www.sedm.de/monkey/s3d/s3dExample.zip

have fun :D

we are on the way....

that's a Wavefront *.obj Model exported from Blender, running on GLFW target

this video shows 17 monkeys. 16 monkeys are just references and not real loaded meshes.

http://www.youtube.com/watch?v=3d2-7E_6A5c&feature=g-upl&context=G2748571AUAAAAAAAAAA

the source for this demo:

Import s3d

	Field cam:Camera, light:Light, mesh:Mesh
	
	Field ref:MeshRef[16]
	Field refTurn:Vector[16]
	
	Method OnCreate()

		cam		= CreateCamera
		light	= CreateLight
		mesh	= LoadMesh("monkey.obj")
				
		PositionEntity mesh, 0.0, 2.0, -4.0		
		PositionEntity light, 0.0, 5.0, -8.0
		CameraClsColor cam, 0.3, 0.6, 0.9
		
		'let's create some monkeys
		Local x:Float = -4.0
		Local y:Float = -3.0
		Local z:Float = -16.0

Nice!

Nice job!

I only saw the video because I could not install your apk on 4.0.3 Ice Cream Sandwich. I'm using a custom rom on my Vibrant called ICS Passion 10.6.

Ok, i was able to get your apk running on my phone.

I did the following:
1. I used root explorer to copy your apk to the \system\apps folder.
2. I rebooted my phone in recovery, and cleared the Dalvik Cache.
3. I rebooted phone again, and was able to run your apk just fine.

I only see one monkey head, and it looks great!!

Restart!

S3D is now again at version 0.1. I've added the greatful code from the "Master of Desaster" Mark Sibly and enhanced the code like i can do.

The module : http://www.sedm.de/monkey/s3d/s3d.zip
The 17 Monkeys Example: http://www.sedm.de/monkey/s3d/s3d17monkeys.zip

the demo doesn't work with GLFW, i've no idea why. I've just renamed the files so you not must edit your build config, and now it just will work on iOS and Android.

If you want to use custom models with S3D, here are some things you have to note:

1. the mesh must have texture coordinates (unwrap your mesh!)
2. at now you can only load Wavefront Object (*.obj) models with S3D
3. export your model with texture coordinates, uv coordinates and triangulate it. For Blender 2.6x: select "Include Normals" and "Triangulate Faces" in the export options.

If you want to use Wavefront Objects directly, add "|*.obj|*mtl" to the CONFIG.TXT. Otherwise you have to rename the file extension to "txt"

The plan is now to create a full 3D Engine which is to use like Blitz3D. Next step is to implement AABB bounding boxes for simple collisions

@Jason W & bruZard, thanks for the info - might try it on my Ice Cream Sandwich soon

The "Game" is over, now it is a project and i call it "S3D".

Today it is just a really small update:

added	: ScaleEntity:Void(entity:Entity, x:Float = 1.0, y:Float = 1.0, z:Float = 1.0)
changed	: Entities do not more ignore his scale factor
changed	: cleanup source
changed : source splitted

http://www.sedm.de/monkey/s3d/s3d.zip

the next big thing are real cameras. the whole scene must be transformed if you move or rotate the camera. Then the "ObjLoader" Class has to be extended for more flexibility, more then one texture layer und for so many things that i think this thing will never be ready :)
Animations are a big theme, i've atm no idea about animations with vertex buffer objects ... but i think thats just a hole to jump over that.
once again: excuse me for my bad english ;)
