Raw data preview module
Raw data preview module
Embedded Files
Raw Predict Engine simulations are stored in *.exr files. They contain :
an XML header with informations about the image, the simulation conditions and the machine that was used for rendering,
an array of named textures with HDR information : each texture is called a layer and represents a specific value. A layer can contain an RGB or XYZ texture (the processed output for instance), a vector (the normals for instance), a float (the depth for instance) or an integer (the material index for instance).
The raw data preview module is designed to visualize all the layers contained inside a raw Predict Engine simulation.
The window contains two widgets :
the settings widgets on the left contains informations and settings on the current layer. The available data depends on the type of the layer (rgb, vector, float,...).
the preview widget on the right contains a preview of the current layer (center), display settings (header) and a list of all available layers (footer).
Using this module, the save button has the following options :
LDR output : the processed output (the image currently displayed on screen) saved to a *.png file.
RGB and XYZ layers
RGB and XYZ layers
Layers of type "RGB" or "XYZ" contain HDR data stored in Vector3. The settings widget contains :
an histogram of the values,
mapping settings to control the exposure and gamma of the image, or to display one of the channels in false colors.
Vector layers
Vector layers
Layers of type "Vector" contain normalized vector data stored in Vector3. Each vector channel contains data in the range [-1;1] and is displayed in the corresponding RGB channel. The settings widget does not contain any settings.
False color layers
False color layers
Layers of type "false color" contain HDR data stored in floats, integer or unsigned integer. The settings widget contains :
an histogram of the values,
mapping settings to control the color map and (for floats only) ranges of data displayed on screen.
