RENDERER USED: Electrogig 3D-go TOOLS USED: CorelDraw! 4, Paint shop pro RENDER TIME: 8 hours HARDWARE USED: Sun Sparc IMAGE DESCRIPTION: This image was originally rendered as part of an Electrogig-course at Delft university of Technology. This explains the subject: it was obligatory to render a presentation of a product. I chose this petrol-burner as my subject because it is a good, timeless design. More important is that it is very suitable for rendering: the product is built up from fairly basic shapes, so it can quite easily be modelled. It consists of several different materials, including some highly reflecting ones, which always give great effects in a rendering. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I divided the product in several parts, like the outer box, the fuel tank and the burner itself. These parts were modelled seperately using boolean operations on basic shapes like cones, cubes and cylinders. For some parts of the burner operations like extrusion along a path would have been far easier, but this is not possible with Electrogig. When everything was modelled, I put it all together and started with the materials. Electrogig uses four attributes to define a material: diffuse, specular, reflection and transperancy. Bump maps can be added too. I could use the normal attributes for materials like chrome and copper. The box was more difficult. When I had the right colour, I experimented with bump maps, because the box has a slightly bumped surface in reality. When rendered however, they all looked far too bumpy, so I skipped bump maps again. Another interesting problem was the reflecting text sticker. It is a very flat, chrome box. I used Corel 4 to make a Tiff-image of the text. It is possible in Electrogig to add a Tiff-image as a diffuse-map to an object. Simply doing so didn't work because the text appeared on all six faces of the box. I then tried to put the text on a totally transparent box in front of the chrome sticker, but this would ruin the clear reflection (the chrome box became drab grey). Finally I found out that it is possible to add attributes to one side of an object, and this worked great. In the end I added a simple (not too distracting) background: a yellow bump map as sand, and another bump map as "jungle". I had to reduce the reflection value of most materials, especially the box, because they reflected the sand too much. The scene is lightened with a single, slightly yellow, spot light. I rendered the image as a 1000x1000 Tiff-image and used paint shop pro to make a 600x600 Jpeg Image. I deliberately didn't add my name or anything, because I don't like it when I have to edit text away from a picture, and I suppose you don't either.
