Snapshots of SolidWorks Add-On Photoview 360: Scenes (Part 3 of 6)

Snapshots of Photoview 360

Part 3: Scenes

Read the Entire Series: (Part One: The Basics, Part Two: Appearances, Part 3: Scenes)

Scenes provide context and environmental lighting and reflections for models. In this snapshot, we will discuss how to apply a custom backdrop to our model. There are other types of scenes such as studio scenes, which you can drag and drop from the task pane into your graphics window. These pre-made scenes can be found by navigating in the task pane to Appearances, Scenes and Decals > Scenes. You have your choice from basic scenes, studio scenes, and presentation scenes. We will focus on creating our own backdrop and applying appearances to it to create the effect we desire.

Scene: What is Included?

Before we get started on a custom backdrop, there is a difference to be aware of between the environment and scene that PhotoView 360 renders. By navigating to the DisplayManager > Scenes, Lights, and Cameras and choosing Expand Scene, you can see that it consists of the background, environment, and floor. Right click on Scene > Edit Scene; you will see three boxes: one each for background, environment, and floor. These three components together make up a scene.

Background - large 2D images located behind or around the model, locked to either our view point or the model.

Environment - 3D sphere around the model simulating a world that can only be seen in reflections or other environmental effects on the model. Environments are locked to the model.

Floor - Provides a surface under the model to which we can apply appearances, reflections, and shadows. The floor is locked to the model.

Custom Backdrop

To create a custom studio, we will first model a backdrop and area lights. Then we will create an assembly, with the modeled parts, and our USB or model of focus. We will add appearances to the area, lights and backdrop as desired. This process involves touching on lights, but the next snapshot will go further in depth on lighting.

Creating the Backdrop:

Open a new part, and on the right plane, model the following. Note that the dimensions used are particular for this model; if your model is larger or smaller you will want to adjust these.

Extrude this using mid-plane to the desired length, and create a thin feature of 1 mm (the thickness does not matter). Also, the curve is a spline tangent to the horizontal and vertical lines.

Below is the final backdrop without an appearance.

Next, create the area lights. Again, these dimensions are specific to this model.

Create an assembly with the backdrop origin and the assembly origin coincident and a 3-D sketch with three lines to place the area lights.

Place three area lights into the assembly, and mate them to the lights, making the centers coincident to the endpoints and the faces perpendicular to the lines.

Add the model, mating it to the origin of the assembly.

Add appearances of area light to the lights, and the desired appearance to the backdrop, similarly to the last snapshot on appearances. Area light appearances can be found in the Task pane > Appearances, Scenes, and Decals > Lights > Area Light. Drag and drop the appearance to apply. We will add a green color to the backdrop for this model.

We will also add a Pitch Black scene to ensure all the light is coming from the area lights. To do this in the Task pane under Scenes > Basic Scenes, drag and drop Pitch Black into the graphics window.

Finally, we will zoom in on the model in isometric orientation, and create a final render. Adjustments to the area lights may be needed. To increase the light brightness, increase the luminous intensity by going to the DisplayManager > Appearances > Area Light > Edit Appearance > Illumination tab. We will learn how to apply cameras to this scene, to take advantage of the depth of field, later in this series.

The next snapshot will go into depth about different lighting techniques to enhance your render. Suggested Reference for further self-study: PhotoView 360 Step by Step Guide
