The basic structure for creating the illustrations and visuals is as follows.
This can be supplied verbally or by email. Written briefs are usually better.
Using any reference material and information gathered, we begin creating your wireframe model(s). We can send test renderings for you to approve or amend. We can also import 3D models you currently have.
Once the model is agreed, we begin applying texture maps (this could be graphics, colour, texture etc.). Once textured, we begin lighting the scene.
As the image develops we send you test renderings. Again this is for you to approve or amend any part of your image.
Once we are agreed on the final look, size, resolution and format, we can begin rendering the image out on our render farm. The final image is then layered up in photoshop and prepared for final output. The image(s) can be sent via email, ftp or CD.
