In this article and following videos, we will go over how to use 3D Objects in PIXERA.

The supported 3D File Formats are:

• .fbx
• .obj
• .gltf

Custom 3d Object Considerations

UV MAP

UV maps are used to bring the 3D representation of the surface onto a 2D plane, which allows us to correctly reproduce textures or video content on these surfaces.

The UV map defines which pixels from the 2D surface are displayed on the 3D surface, and vice versa.
This follows the usual workflow for textures of 3D objects, there are no deviations from the standard workflow.

Polygon Count

The number of polygons should always be evaluated with regard to both visual detail and performance. In 3D video games, for instance, performance is a critical factor.

In Pixera, this aspect is generally much less significant, since polygons are typically static and not rendered in real time — unless the objects are being moved via tracking.

For projection setups, polygon count is usually not a decisive factor. However, maintaining a healthy balance is still advisable to ensure smooth handling within the GUI.

It is difficult to provide a definitive guideline for the polygon count or level of detail of a 3D model, as this largely depends on the specific setup and practical requirements. More importantly, the necessary level of detail is influenced by how precisely the model needs to be warped and how visible these details are in relation to the projected content.

Object Surface

Unlike usual in 3D editing, in order for Pixera to enable warping on custom 3D models, the surface of these models must be equipped with vertex points.
This is only relevant for projection surfaces. For custom LEDs, this is not a problem and can be ignored.

Import

Depending on the subsequent workflow via projection or LED, it is important how the object is imported into Pixera. It can be imported as a custom screen or custom LED, for example, which offer different options.

Settings

In order to be correctly recognized in Pixera as a 3D object to be played, this must now be set in the object's inspector.

Next, pay close attention to the resolution, as it influences both Pixera’s processing and how the textures (videos) are applied.

When creating the UV map, make sure to consider its format and pixel dimensions, since these values will need to be entered later in Pixera.
These values can be gathered due to the calculation of the pixel.
This can be determined using pixel calculations for the surface. For LED walls, the pixel pitch and how many tiles are used; for projections, the number of projectors and the resolution.
In most cases, a native 1:1 ratio of content resolution to actual pixels on the surface is desired.

After these settings have been configured, no further special steps are required, and you can continue with the standard workflow.
