m_localMetersPerPixelX

float GradientSignal::ImageGradientSizeData::m_localMetersPerPixelX = 0.0f

The meters per pixel in each direction for this image gradient in the image's local space. This accounts for image tiling and frequency zoom, but removes the effects of the transform's scale, since the scale is applied outside of the local space calculations.

m_metersPerPixelX

float GradientSignal::ImageGradientSizeData::m_metersPerPixelX = 0.0f

The meters per pixel in each direction for this image gradient. These help us query the paintbrush for exactly one world position per image pixel.
