Nira – Easily Share and Inspect Your Models and Maps

What is Nira?

Nira is a web-based 3D model viewer that simplifies how users can view, share, and collaborate on 3D assets. With Nira, anyone can interact with high-resolution 3D models directly from a web browser, without needing a high-end computer or specialized software. Whether you’re on a laptop, tablet, or even a smartphone, Nira makes sharing and viewing 3D models accessible to everyone.

The Challenge with Traditional 3D Model Viewing

Software like Reality Capture and DJI Terra are excellent for processing photogrammetry data into detailed 3D models. However, viewing these 3D models typically requires:

A powerful computer with high-end graphics capabilities.
Specialized software to render the model.

This can make collaboration difficult, especially when sharing models with clients or team members who might not have access to the necessary hardware or training.

How Nira Solves This

Nira eliminates these barriers by hosting your 3D models on secure cloud servers. Once uploaded, the models can be shared via a link, allowing anyone to view and interact with them in high resolution. This means:

No special hardware or software needed.
Real-time rendering on any device.
Easy collaboration and feedback.

Flexible and Scalable Pricing

Nira offers affordable and flexible pricing plans starting at $19 USD/month. Unlike traditional storage models, Nira doesn’t limit file storage size. Instead, it measures the quality of the model by its triangles, textures, and photos.

Here are the key options:

Data security:

Nira provides robust measures to ensure data confidentiality, integrity, and availability within its platform. Leveraging secure cloud infrastructure from AWS, Google Cloud, Cloudflare, and Quadranet, Nira employs practices like pixel streaming to prevent data extraction, automated proprietary file processing, and region-locked storage options for enterprises. Security is reinforced through 256-bit HTTPS encryption, restricted file access, and the use of Google Identity Platform for authentication. On-premise deployment options offer maximum control for organizations requiring private networks. Systems are designed for resilience with failovers and encrypted storage, while strict human resource policies ensure compliance with security guidelines.

Understanding the Basics of 3D Models in Nira

Triangles: The Building Blocks of 3D Models

A 3D model is constructed from tiny flat shapes called triangles. These triangles are like LEGO bricks for 3D shapes:

More triangles = more detail.
Fewer triangles = faster rendering but less detail.

A low-poly building (fewer triangles) may look blocky.

A high-poly building (more triangles) appears smoother and more detailed.

In Nira, the triangle count determines how detailed your model can be. For instance, the Individual Plan’s 100-million-triangle allowance, provides the flexibility to upload multiple smaller models or one large, ultra detailed model.

Calculating Triangles for Your Model:

To determine the number of triangles in your model:

Export from Your 3D Software: Check the export settings or summary from software like Reality Capture or Blender. The total triangle count is often displayed.
Optimize if Needed: If your model exceeds the triangle limit, use decimation or simplification tools in your software to reduce the count while maintaining necessary detail.

The number of triangles in your 3D model depends on its size and the rendering settings in your photogrammetry or modeling software. For example, when we rendered an initial model in Reality Capture using default settings, it resulted in over 120 million triangles.

This model has been simplified in Reality Capture down to 1 million triangles. So you could theoretically host 100 models within the Individual plan.

This model was simplified down to 40 thousand triangles, the edges of each shingle is less defined.

Textures: The Skin of the Model

While triangles define the shape of the model, textures add color and detail. A texture is like wrapping a photo or painting onto the 3D surface to make it look realistic. For example:

A basketball model’s texture would include the orange surface, black lines, and bumpy details.

Textures in Nira are measured in gigapixels. For example:

A 4K texture map (4096 × 4096 pixels) = 16.8 megapixels.
A 8K texture map (8192 × 8192 pixels) = 67.1 megapixels.

Calculating Total Textures:

Understand Your Texture Maps: Each texture map corresponds to a specific part of your model. For example, a complex building model might have multiple texture maps for walls, windows, and roof.
Compute Pixel Count: Multiply the width and height of each texture map. For instance:
- A 4K texture map = (16.8 MP).
- A 8K texture map = (67.1 MP).
Sum Up All Textures: Add the pixel counts of all texture maps used in your model. Divide the total by 1,000,000 to convert to megapixels (MP).

Our example model consists of 536 megapixels (0.5 Gigapixels) in texture detail. This model was captured using the 220 photos @ 20 megapixel camera on the Mavic 3 Enterprise camera.

Photos: Linking High-Resolution Images

Photogrammetry models rely on high-resolution photos for detail. With Nira, you can upload these photos and link them to your 3D model for easy navigation and inspection.

This aspect counts towards the photos and is calculated by the amount of photos multiplied by the cameras megapixel. In our example model, the photos amounted to 4.6 Gigapixels (20 x 220)
