Constructor Detail

MaterialHelper

public MaterialHelper(java.lang.String blenderVersion,
                      BlenderContext blenderContext)

This constructor parses the given blender version and stores the result. Some functionalities may differ in different blender versions.

Parameters:

blenderVersion - the version read from the blend file

blenderContext - the blender context

Method Detail

toMaterialContext

public MaterialContext toMaterialContext(Structure structure,
                                         BlenderContext blenderContext)
                                  throws BlenderFileException

This method converts the material structure to jme Material.

Parameters:

structure - structure with material data

blenderContext - the blender context

Returns:

jme material

Throws:

BlenderFileException - an exception is throw when problems with blend file occur

getParticlesMaterial

public Material getParticlesMaterial(Material material,
                                     java.lang.Integer alphaMaskIndex,
                                     BlenderContext blenderContext)

This method converts the given material into particles-usable material. The texture and glow color are being copied. The method assumes it receives the Lighting type of material.

Parameters:

material - the source material

blenderContext - the blender context

Returns:

material converted into particles-usable material

getMaterials

public MaterialContext[] getMaterials(Structure structureWithMaterials,
                                      BlenderContext blenderContext)
                               throws BlenderFileException

This method returns the table of materials connected to the specified structure. The given structure can be of any type (ie. mesh or curve) but needs to have 'mat' field/

Parameters:

structureWithMaterials - the structure containing the mesh data

blenderContext - the blender context

Returns:

a list of vertices colors, each color belongs to a single vertex

Throws:

BlenderFileException - this exception is thrown when the blend file structure is somehow invalid or corrupted

rgbToHsv

public void rgbToHsv(float r,
                     float g,
                     float b,
                     float[] hsv)

This method converts rgb values to hsv values.

Parameters:

r - red value of the color

g - green value of the color

b - blue value of the color

hsv - hsv values of a color (this table contains the result of the transformation)

hsvToRgb

public void hsvToRgb(float h,
                     float s,
                     float v,
                     float[] rgb)

This method converts rgb values to hsv values.

Parameters:

h - hue

s - saturation

v - value

rgb - rgb result vector (should have 3 elements)
