Viewing Your scene

USD Presenter offers 3 modes of Rendering Quality: Draft, Preview and Photo. There are also 3 modes of USD Review: Present, Comment and Approve. Explore the modes below.

The 3 different rendering modes can be mixed with the 3 different modes of review as desired.

Rendering Modes

Draft

In Draft Mode, the default rendering mode for USD Presenter, the usd file is displayed in our RTX Real-time renderer. This is a very powerful, real-time exploration mode, capable of displaying heavy, complex scenes with a smooth, highly responsive speed. It offers noise free, beautiful presentations of your scene, with rich textures, realtime reflections, and compelling lighting. This mode is intended for speed over quality, and makes it possible to review large amounts of data without fear of performance.

Preview

In Preview Mode, your scene will be rendered with our RTX Interactive (Path Tracing) renderer. This now renders your scene with highly accurate reflections, refractions and caustics to create a much more realistic look. Lighting is correctly calculated with path tracing, and multiple bounces of light will illuminate your complete scene. Whilst this mode is no longer “real-time” and performance will be slower than Draft mode, you will see a much higher quality representation of your work. You will see the scene “settle” as it renders samples. The longer it renders, the higher quality the image. Textures and details will become sharp.

Photo

Photo Mode is our most accurate rendering mode, for truly photo real rendering. It is no surprise that this uses our Accurate (Iray) renderer. This mode is for uncompromised quality over interactive speed. Here the usd file will be extremely well presented for super accurate reflections, refractions, caustics, texture quality, lighting and effects. It also supports the highest fidelity in materials. This is good for final review at maximum quality. Like Preview mode, viewing in this mode will take time to resolve to full quality and will not be as responsive as Draft or Preview mode.

Review Modes

Present

Present Mode is the default Review Mode for USD Presenter. In this mode, the user interface is very clean and simple. Options and tools are hidden away to allow for a near full screen review of your file. The only main element is the floating Main Toolbar in the lower middle portion of the screen (see Main Toolbar section below)

Comment

In Comment Mode, the user interface expands to offer new tools and options. Starting at the top, you have a visibility menu to control the viewport overlay options. On the top you have the Camera Toolbar (see Camera Toolbar). On the right, you have the Right Toolbar (see Right Toolbar). There are two new floating elements for adding Markups and Waypoints (see Markup Tool and Waypoint Tool)

Approve

In Approval Mode, the list of Markups is available for approval or rejection. The floating toolbar changes slightly to now offer two new buttons. Accept and Reject. A green arrow, or a red “X”.

Floating Toolbar

The floating toolbar is a movable user interface element with a lot of useful navigation features and tools.

3. WHITE MODE

This mode overrides all the materials in the scene with a default “DebugWhite” material. This is very useful for viewing a scene with the distraction of color and texture. Just lighting

4. MEASURE TOOL

The Measure Tool helps you truly understand the scale and makeup of your design in a physical sense. This tool lets you pick two meshes and measure between them or make measurements across any number of meshes using the various sub-tools Point-to-Point, Multi-Point, Angle, and Area.

Control over the dimension is available through a min/max/center toggle which adjusts the type of measurement. Min is the minimum distance between two objects. Max is the maximum distance between two objects. And finally, Center is the distance between the centers of each mesh. Note that you can control the direction of the measure against the X, Y or Z axes as desired.

Other options allow you to set the unit of measure, color of the dimension, precision shown in the dimension’s text as well as a general height of the text.

Dimensions can be selected and deleted.

Option	Description
Measure Selected Mode Row	Mix, max center toggle adjusts the type of measurement.
Measure Selected	Measures the distance between two prims using the Measure Selected Mode type.
Area	Measures an area between the selected points.
Angle	Measure the acute and obtuse angles in a corner.
Multi-point	Measures distance between multiple points.
Point-to-point	Measures distance between two points
Snap To	Vertex: Objects snap to the vertices of another object Midpoint Center Edge: Objects snap to the edges of another object. Pivot
Constrain To	StageUp (X, Y, Z)
Display XYZ	Visualize Axis Dimensions in both Local and World coordinates. Default is None
Units	Controls display of measurements in common units (centimeter, inch, millimeter, etc.).
Precision	Determines how many decimal places to use before rounding.
Label Size	Determines the size and legibility of the display.
Line Color	Defines the color of the Measurement Indicators.

5. Sun Study Tool

This Omniverse Extension allows users to review models with accurate sunlight. You need to set Dynamic Sky to your scene using Omniverse Create prior to using the sun study tool in Omniverse USD Presenter.

The Sun Study interface allows you to play through a day and night 24 hr cycle and watch the change in lighting dynamically. You can set minimum and maximum markers to shorten the length of the cycle to your desired times. You can scrub the timeline and select a specific time of day.

Note

Many tools give GPS coordinate data. This is not the same as latitude and longitude. GPS coordinates include a North/South by East/West designation. To convert to latitude and longitude, invert West or South designations with a negative value. For example convert 22 degrees South (22.00’000 South) to –22.00.000 and 35 degrees West (35.00’000 West) to –35.00.000. Ignore East and North designations, because they’re both positive and do not require any alterations to work.
