If you’re trying to recall what model rendering is, as said by Wikipedia — it is the automatic process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of computer programs. Rendered objects would contain geometry, viewpoint, texture, lighting, and shading information as a description of the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file.
Back to where I started, rendering is a nightmare for frontend developers because rendering is a time-consuming process. Rendering is required in many types of business websites. For example, a custom apparel designing website, or a web-based automobile customization tool. One sure fact is that no visitor of any website is going to wait minutes to get a rendered view of an object. So, our challenge is to get the rendering completed in minimal time as possible.
In the recent past, I built a web application for Shimble. Shimble is a marketplace for tailors. It connects the global tailors with the customer and offer a range of high-quality custom clothing, sized to perfection, with huge savings.
The challenge I faced here is — to render one model it took around 3–4 minutes on a normal laptop. It took even more time on computers with lower specifications. Obviously, the application was not qualified to launch on the production scale.
I had to burn a lot of fuel to find a solution, I tried a variety of options and each and every one of it came with a major setback. Mostly in the form of the visitor needing to install additional plugins.
WebGL provided the best results for the work, but being a client-side application, website visitors need to have a computer with good specifications to access the tool. Then this thought occurred to me — Would it work if we render the model in server-side using a client-side application.
I had to try it out. I did. And it worked.
By using a chromium browser installed on the server-side, I transferred the rendering requests to the high-end server side. With the new architecture, the rendering was completed under 30 seconds, which was a reasonable time for the visitor to wait to see the rendered view of the apparel they just customized.
