Method Detail

blend

public Image blend(Image image,
                   Image baseImage,
                   BlenderContext blenderContext)

Description copied from interface: TextureBlender

This method blends the given texture with material color and the defined color in 'map to' panel. As a result of this method a new texture is created. The input texture is NOT.

Parameters:

image - the image we use in blending

baseImage - the texture that is underneath the current texture (its pixels will be used instead of material color)

blenderContext - the blender context

Returns:

new image that was created after the blending

getTinAndAlpha

protected void getTinAndAlpha(java.nio.ByteBuffer data,
                              Image.Format imageFormat,
                              boolean neg,
                              float[] result)

This method return texture intensity and alpha value.

Parameters:

data - the texture data

imageFormat - the image format

neg - indicates if the texture is negated

result - the table (2 elements) where the result is being stored

blendPixel

protected void blendPixel(float[] result,
                          float[] materialColor,
                          float[] color,
                          float textureIntensity,
                          float textureFactor,
                          int blendtype,
                          BlenderContext blenderContext)

This method blends the texture with an appropriate color.

Parameters:

result - the result color (variable 'in' in blender source code)

materialColor - the texture color (variable 'out' in blender source coude)

color - the previous color (variable 'tex' in blender source code)

textureIntensity - texture intensity (variable 'fact' in blender source code)

textureFactor - texture affection factor (variable 'facg' in blender source code)

blendtype - the blend type

blenderContext - the blender context

blendHSV

protected void blendHSV(int type,
                        float[] materialRGB,
                        float fac,
                        float[] pixelColor,
                        BlenderContext blenderContext)

The method that performs the ramp blending.

Parameters:

type - the blend type

materialRGB - the rgb value of the material, here the result is stored too

fac - color affection factor

pixelColor - the texture color

blenderContext - the blender context

copyBlendingData

public void copyBlendingData(TextureBlender textureBlender)

Description copied from interface: TextureBlender

Copies blending data. Used for blending type format changing.

Specified by:

copyBlendingData in interface TextureBlender

Parameters:

textureBlender - the blend data that should be copied

prepareImagesForBlending

protected void prepareImagesForBlending(Image target,
                                        Image source)

The method prepares images for blending. It generates mipmaps if one of the images has them defined and the other one has not.

Parameters:

target - the image where the blending result is stored

source - the image that is being read only
