Refining the 3D Model and Adding Details


The addition of details is one of the heaviest items in the project. It is at this moment that the 3D model becomes more complex. The profound changes to the project at this stage are time consuming and it is sometimes even more profitable to remodel part of the building rather than try to modify it. It is therefore advisable to make all volume changes.

Creating, Adapting and Applying Textures – Refining Lighting

If it is quite possible to create a beautiful image without any texture or even color, a poorly lit scene will never give a good result. The process of applying materials to architectural elements is therefore intimately linked to the lighting of the stage. A material is also seldom usable as such in another project.

In 3D computer graphics, each material is defined by an impressive amount of parameters: ambient, diffuse and specular color, texture, transparency and others, the aim being to best simulate the appearance of the actual material in the final image.

Stage lighting is for me the most complex and exciting part of 3D computer graphics. In some cases I use a specific rendering software, Maxwell Render, but the calculation times are very long and rarely profitable in production. I most often prefer to simulate indirect lighting with attenuated light sources. Implementation and testing times can be relatively long for some complex projects … but the rendering is very fast compared to specialized rendering engines in global illumination

Calculation of computer graphics in high definition

The choice of the resolution of the image (in pixels) depends on the use to be made of the image. An image intended solely for inclusion in a website may be content with a relatively low resolution. An image that will spread over a real estate promotion board 4 meters by 2 will require a much better resolution, especially if the image can be examined closely.

When calculating the final image, it is possible to calculate separately the different “passes” of the image: diffuse colors, shadows, reflections, etc. This makes it possible to refine the image very precisely during the final compositing. I also systematically calculate the alpha channel that separates the 3D model from its bottom. This allows me to quickly change a sky or the environment of a computer image.

Note: once the 3D model is modeled, 3d architectural modeling services, textured and illuminated, the calculation of additional images represents a negligible cost.

Image Editing and Final Compositing

The few imperfections not detected during the previous phases are corrected in image editing with Photoshop. The colorimetry, brightness or contrasts of the image can also be modified to suit an existing photographic environment, as is the case for integrations in the site.

The compositing will then give life to the computer image by creating an atmosphere with the addition of vegetation, silhouettes or vehicles. You can vary the shadows or the intensity of the reflections, change the color of a specific element or add special effects. Compositing also helps to energize and balance the composition. Finally, I attach a primary importance to the relationship of the computer image with the blank page, which allows it to adapt to all uses. Compositing is the phase that really transforms a good image into a stunning image that will be remembered!

Delivery of the final image to the customer or his printer

Once the final image has been validated by the client, it is delivered either on physical media (print, CD-R or DVD-R), or sent by e-mail if its size is not too important. Beyond 2 or 3 MB, we provide a link to the computer file hosted on our web server. It is then possible for the client to download files of several hundred MB.
