User Manual

 Disable View LUT Shaders: OpenGL shaders can often dramatically accelerate View
LUTs, but this can occasionally involve small trade-offs in accuracy. This setting will
force Fusion to process LUTs at full accuracy using the CPU instead. Try activating this if
View LUTs do not seem to be giving the desired result.
 Use Float16 Textures: If your graphics hardware supports 16-bit floating-point textures,
activating this option will force int16 and float32 images to be uploaded to the viewer as
float16 instead, which may improve playback performance.
 Texture Depth: Defines in what depth images are uploaded to the viewer.
–
Auto: The Auto option (recommended) lets Fusion choose the best balance of
performance and capability.
–
int8: Similar to the Use Float16 Textures switch, this option can be used to force
images to be uploaded to the Display View as int8, which can be faster but gives
less range for View LUT correction.
–
Native: The Native option uploads images at their native depth, so no
conversion is done.
 Image Overlay: The Image Overlay is a viewer control used with Merge and Transform
tools to display a translucent overlay of the transformed image. This can be helpful in
visualizing the transformation when it is outside the image bounds but may reduce
performance when selecting the tool if cache memory is low. There are three settings
to choose from: None, Outside, and All.
–
None: This setting never displays the translucent overlay or controls, which can
reduce the need for background renders, in some cases resulting in a speed up of
the display.
–
Outside: This will display only those areas of the control that are outside the bounds
of the image, which can reduce visual confusion.
–
All: Displays all overlays of all selected tools.
 Smooth Resize: This setting can disable the viewer’s Smooth Resize behavior when
displaying floating-point images. Some older graphics cards are not capable of filtering
floating-point textures or may be very slow. If Smooth Resize does not work well with
float images, try setting this to flt16 or int.
 Auto Detect Graphics Memory (MB): Having Fusion open alongside other OpenGL
programs like 3D animation software can lead to a shortage of graphics memory. In
those cases, you can manually reduce the amount of memory Fusion is allowed to use
on the card. Setting this too low or too high may cause performance or data loss.
 Use 10-10-10-2 Framebuffer: If your graphics hardware and monitor support 30-bit
color (Nvidia Quadro/AMD Radeon Pro, and some Nvidia GeForce/AMD Radeon), this
setting will render viewers with 10 bits per primary accuracy, instead of 8 bits. Banding
is greatly reduced when displaying 3D renders or images deeper than 8-bit.
