3d lib

.	(Posted 2008-01-12)

Development is going slowly, because of school stuff.. I managed to add fog (which took like a minute), but there's a shot anyway (I like screenshots:). By the way, the code for the library looks like this:

Strict
Import "ngl.bmx"


Local Gfx:NGraphics = NGraphics.Start(800,600)
Local Cam:NCamera = NCamera.CreateCamera()
Cam.Move(30,10,-60)
Cam.SetClearColor(163,192,255)
Cam.EnableFog(30,100,163,192,255)
HideMouse

Local Cube:NEntity = NEntity.CreateCube()
Cube.LoadTexture("crate.jpg")
Cube.EntityAlpha 0.3

Local Mesh:NEntity = NEntity.LoadMesh("md2/fish.md2")
Mesh.ScaleMesh(0.3,0.3,0.3)

Local Light:NLight = NLight.CreateLight()
Light.Translate(20,40,0)
Light.Ambient(255,255,255)
Light.Diffuse(255,255,255)

Local Map:NEntity = NEntity.Heightmap("hmap.bmp")
Map.LoadTexture("grass.png")

Repeat
	'Camera control
	If KeyDown(KEY_LEFT) Then Cam.Move(-0.3,0,0)
	If KeyDown(KEY_RIGHT) Then Cam.Move(0.3,0,0)
	If KeyDown(KEY_UP) Then Cam.Move(0,0,0.3)
	If KeyDown(KEY_DOWN) Then Cam.Move(0,0,-0.3)
    
        Mesh.Animate()
 
        Gfx.Render
	Gfx.Swap(1)
Until KeyHit(KEY_ESCAPE)

particles

The particle engine is pretty much done. Switched to point sprite opengl extension, which is pretty fast. Z-sorting more than halves the fps though :/. This is required for alpha particles.

Added support for parent/child, added CreateSprite (which just creates a quad which consists of 2 triangles), and finally heightmap loading. This just loads the heightmap, and the result is a normal entity/mesh..

shaders

(Posted 2008-01-04)

Added support for GLSL shaders. It was pretty simple, but the real difficulty is creating new shaders.. but that is left for the users :).

Here's a basic toon shader:

and another one:

Today I've mostly been watching The League of Gentlemen, so I didn't get much done. I added FreeEntity,FreeTexture and AddMesh methods, and optimized list creating.. now the list is only created just before rendering if necessary, instead of every mesh operation, except for copyentity. This way copying an entity uses the old mesh until it is modified.

New project, 3d lib

(Posted 2008-01-01)

I've been working on an OpenGL 3D library, I've got the basic stuff of entities, cameras, movement etc working, and MD2 loading with animations. I also have texture loading working. I still need to work on the particle system.. Lights are pretty much done too.

Today I've mostly doing optimizing, and it is starting to be performing decently. Statistics:
1000 MD2 entities, with textures and alpha translucency, 1000 triangles each totaling 1 million triangles, and I get ~47fps at 800x600 resolution. With 100 entities, I'll get 280fps. This is with 8400M laptop gfx card.

Random shots:
