Initialize Initializes the ActiveShade window. To keep the ActiveShade
window current, you need to choose Initialize after transforming, modifying,
or otherwise changing geometry. If you have turned off Automatic
Reinitialization, you also need to choose Initialize after you update a mapped
material.
Rendering can be slow. The initialize pass is meant to take care of the most
time-consuming portions of rendering, to allow the update pass to take place
as quickly as possible. Initialization includes the following steps:
■ Evaluate the scene geometry into meshes.
■ Apply space warps.
■ Do transformations and clipping.
■ Evaluate textures and shade materials.
■ Perform optimizations to speed later processing, such as merging fragments
from the same surface that are in the same pixel.
The result of initialization is a buffer. This is a compressed rendering that, like
a
G-Buffer on page 7795 , contains the rendering plus additional information
used by the second step, updating.
During the initialize pass, progress is indicated by a row of pixels (white by
default) that traverses the top edge of the ActiveShade window.
Update Updates the ActiveShade window. Updating shading takes the buffer
created by the first pass, initialization, and uses information in that buffer to
change the color of pixels when you make changes to lights and materials in
the scene.
During the update pass, progress is indicated by a row of pixels (white by
default) that descends the right edge of the ActiveShade window.
To keep the ActiveShade window current, you need to choose Update Shading
if you have previously turned off Automatic Shading Update.
Select Object (viewports only) When on, you can select an object in the
ActiveShade window by clicking. You can select only one object at a time.
When an objects is selected in the ActiveShade window, the Initialize pass
resamples textures for that object alone. This improves the window's rendering
speed, and is useful when you are adjusting texture display.
Toggle Toolbar (viewports only) Toggles display of the ActiveShade window
toolbar in viewports.
