good or bad cgi?
The artists at Red and Gray spend a lot of time analysing the images they prepare in the pre-production phase to see where extra detail can be added within the budgetary limitations of the project to maximise the realism and final appeal of their finished work.
What, at first glance appears to be a good CGI, with further study, may turn out to be not so good after all. Use our generic example points here to learn about some of the subtleties of CGI quality and the effect it can have on the overall power of the image.
LET’S EXPLORE THE SUBTLETIES OF GOOD AND BAD CGI

- 01 // wall
Flat colour only. No visible texture or surface distortion. - 02 // sunlight spill
Flat colour only. No visible texture or surface distortion. - 03 // plants
Very simple flat texture to leaves. Minimal shine or translucent light diffusion through the foliage. Plant pots have unrealistic textures. - 04 // sofa fabric
Fabric described by different patches of colour only. Areas in shadow appear very flat and unrealistic. - 05 // fur cushion
Appears coarse and unrealistic. The hairs lack subtlety and the effect is unconvincing. - 06 // table and objects
Each object has a texture that describes the material in a simplistic way with a lack of refinement. Bowl appears to float. - 07 // stitched cushion
The cushion intersects with the sofa. Whilst it appears to be stitched, the texture lacks definition, surface form and realism. - 08 // floor and rug
No visible surface characteristics other than the pattern is visible. Plant leaves intersect with the floor.

- 01 // wall
Natural surface discolouration. Texture to describe surface characteristics. - 02 // sunlight spill
Subtle glow from a hidden window enhances the wall and adds extra punch. - 03 // plants
Gloss shine and subtle translucency to the leaves make the plants realistic. Plant pots are described with convincing aged ceramic. - 04 // sofa fabric
Velvet fabric is convincing with realistic patchiness and texture. Shadow areas still describe the form of the sofa and texture characteristics. - 05 // fur cushion
Fine hairs and realistic clumping give the impression of a soft cushion. - 06 // table and objects
Glossy shine to the wood on the bowl and convincing pages to the books. - 07 // stitched cushion
Surface form is described accurately with highlights and texture attributes to convince the viewer of the shape of the object. - 08 // floor and rug
Tiles have surface attributes like gloss and shine and the rug is a convincing wool texture.
