Helper class for creating a Model from a .cgeo blob.
The .cgeo blob is typically received from a web service or a local file.
Usage:
let geoModel = new cee.geo.GeometryModel();
let modelGenerator = new cee.geo.CgeoModelGenerator(buffer, geoModel);
modelGenerator.buildModel();
** CGEO format documentation **
Int Magic Number (2072003)
Int TextureCount
Int PartCount
Textures (TextureCount number of this block):
Int Index : Zero based index
Int Width : Width of texture in pixels (see note below about dimensions)
Int Height : Height of texture in pixels (see note below about dimensions)
Int WrapMode : 1: Clamp To Edge, 2: Repeat
Int MinFilter : 1: Nearest, 2: Linear, 3: Nearest Mipmap Nearest,
4: Nearest Mipmap Linear, 5: Linear Mipmap Nearest,
6: Linear Mipmap Linear
Int MagFilter : 1: Nearest, 2: Linear
ubyte\*Width\*Height pixelData : First pixel is lower left corner
Parts (PartCount number of this block):
Int PartId
Int Color (r,g,b,a)
Int NumVertices
Int HasNormals (1=true, 0=false)
Int TextureIndex (-1 for none)
Int NumPrimitives
Int VerticesPerPrimitive
Vertices:
3*float vertex x,y,z
Normals:
3*float vertex nx,ny,nz
TextureCoordinates:
2*float vertex s,t
Indices:
Notes:
Texture dimensions: Generally we recommend using textures where the dimensions (height and width) are a power of two (2,4,8,16, etc).
Non-POT2 texture are partially supported in WebGL, but requires the sampler to be configured without MipMaps and with wrap mode set to
ClampToEdge.
Color is r,g,b,a packet into one integer. Example with float colors (0..1 per component):
int intOpacity = (int)(opacity*255.0f);
int intColor = (int)(color.r()*255.0f)<<24 | (int)(color.g()*255.0f)<<16 | (int)(color.b()*255.0f)<<8 | intOpacity;
