Topography > ModelInfo > Properties
ModelInfo settings for a topo file are used to define core functions of how the topo object reacts to layer scaling and
positioning, UV mapping, external Art-Net control (e.g. for remote control of positioning), and keystone/warp.
The Properties tab has four settings.
+ Fixed Position checkbox: causes the object's position and scale to be disconnected from Art-Net control. These
Art-Net controlled parameters will now control the texture position and size on the object instead. Object position
and scale may still be adjusted using the Projection Editor. Projection mapping will not be accurate unless the
models have the fixed position checkbox checked!
+ Emissive checkbox: causes the object to be fully lit. Overrides Art-Net controlled Ambient and Spot lighting
fixtures.
+ Mask File: 8-bit index number for folder.file of vignette of PNG files to be used as a mask on the object. Files will
be force-fit onto the object based on the object's size not the size of the mask. [Tip: Masks should typically only
be used on topo or svg files as the result of applying a mask to an object with more than one face may be
undesirable unless great care is taken with the mask.]
+ Face Cull pop-up: selects which faces of the object are not drawn. You can choose not to render the front or rear
faces of an obj file.
Topography > ModelInfo > Tex Camera
The Tex Camera tab allows you to create a custom UV map for the topo file based on a specific viewing location
unique to that topo file. This viewing location can be different from the viewing position implied by the UV map
settings in the original file. The Tex Camera causes Mbox to apply the texture to the topo object in a manner that
allows the image to appear undistorted from a specific viewpoint - by default topo objects are UV mapped in a "flat
map" manner where the optimal viewing position is perpendicular to the origin of the topo object.
This tab uses the same setup procedure and settings as the Projection > Camera Setup tab. Refer to page 204 for
details.
Topography > ModelInfo > Controls (Mbox Designer Only)
ModelInfo controls can be added to an object to allow additional Art-Net patched into the Mbox server to modify four
aspects of the object - position, rotation, texture position, and opacity. Controls should be added with care and may
require consultation with a PRG Mbox specialist before use.
