Study Notes
Colours and Textures in 3D Modelling, Games, and Multimedia
- Digital games combine various art forms, including writing, sculpture, music, storytelling, cinematography, and painting.
- Colour is a crucial element in 3D modelling, setting the tone and influencing character personality.
- The perceived colour of an object depends on its surface properties, illumination, lighting sources' geometry, and surrounding objects' colours.
- Colour is a wavelength in the electromagnetic spectrum.
- Colour models, including RGB (Red, Green, Blue), CMYK (Cyan, Magenta, Yellow, Black), and HSL (Hue, Saturation, Luminance), define colours.
- RGB is additive; red + green + blue = white; colours are used in screens, projectors, and video cameras.
- CMYK is subtractive; colours are used in printers.
- The human visual system interprets colour by stimulating visual pigments in retinal cones.
- Color palettes are crucial for the success of visual projects, such as digital games, and should leverage psychological/cultural meanings behind colours. Colours can be used to highlight, diffuse information, or show feelings/moods.
Colour Palettes for Various Visual Projects
- Several visual projects, including digital games, movies, and paintings, have associated colour palettes that have been analysed and studied.
- These analyses cover the nuances of colour and their effects on mood, emotion, and visual appeal.
- There are various examples of colour palettes from different games (e.g., Final Fantasy X, Silent Hill 2, The Elder Scrolls V: Skyrim, Journey, Halo 4, The Last of Us, The Martian, The Revenant, Alice Through the Looking Glass, 1917, and Joker: Folie à Deux).
- A colour palette is of paramount importance for the success of a visual project.
Methods to Choose a Colour Palette
- Analysts have noted various colour schemes, including analogous, monochromatic, triad, complementary, and tetrad. These schemes are useful in creating balanced and harmonious colour palettes.
- Useful tools for choosing colour palettes include websites like color.adobe.com, paletton.com, and colorpalette.imageonline.co.
Colour Blindness and its Importance
- There is a significant consideration of the importance of colour blindness when it comes to creating visual projects where colours are important.
- Understanding the challenges and nuances presented by colour blindness is important for creating more inclusive designs.
Materials and Surface Appearance
- Defining the appearance of a surface in 3D models involves setting colour and surface reflectivity properties, including diffuse, specular, transparency, and metallic properties.
Textures
- Texturing involves applying 2D images to 3D objects to add realism and aesthetic appeal.
- Texturing creates more aesthetic environments and efficiently simulates real textures.
- A variety of textures allows for the creation of complex 3D content.
Mipmaps
- Mipmaps are sequences of textures with different resolutions, which helps improve rendering performance by reducing time and memory requirements. They use the Level of Detail (LOD) principle, where textures closer to the camera are higher resolution.
Applying Textures
- Textures are applied onto 3D surfaces using various methods like projection, and wrapping.
- Projection projects the texture onto the 3D surface; wrapping stretches the texture to fit the surface.
- Different projection methods include Flat/Planar, Cubic, Cylindrical, and Spherical projection.
Colour/Diffuse Maps
- Colour/Diffuse map contains colour information. They are used for computing the colour of light reflected from a 3D surface, and can be used, for example, to add skin tones in a 3D model.
Light Maps
- Light maps pre-process lighting effects for better performance, mainly used in static objects.
Bump Maps
- Bump maps alter the orientation of surface normals using greyscale images to simulate roughness without modifying the surface itself.
Specular/Reflection Maps
- These maps simulate how a material reflects light across the surface.
Normal Maps
- Normal maps work similar to bump maps but use RGB values instead of greyscale, adding more detail to simulated objects. Normal maps are useful for increasing the realism and detail in low-polygon models.
Ambient Occlusion
- Ambient Occlusion maps simulate soft shadows by considering ambient lighting, which produces a greater sense of realism.
Heightmaps
- Heightmaps store elevation data in a greyscale image, modifying the geometry's vertical position creating the illusion of depth and contour. Mostly used in terrain generation.
Displacement Maps
- Similar to heightmaps, displacement maps change vertices and surface normals to provide more intricate and realistic detail by affecting the surface geometry of the object being modeled.
Triplanar Mapping
- Triplanar mapping is useful for objects with no UV coordinates. It projects textures from multiple angles and blends them based on object normals, adding more depth and completeness to these objects.
Environment Maps
- Environment maps allow the reflection of the environment onto reflective surfaces.
Realistic Texturing
- Combining various methods, including maps, to create more realistic textures in the 3D model.
