Realistic rendering techniques
I can add render to a 3D sketch to show material texture.
Lesson details
Key learning points
- Adding material, colour and texture can enhance the drawing.
- By adding tone and texture to the sketch through rendering, we can show how the object will look and feel.
Keywords
Rendering - to add details like shading, texture and depth to a sketch to make it appear more realistic
Texture - how something feels, or looks like it would feel, if touched
Shading - adding shadow to a sketch to make it appear more realistic
Tone - the lightness or darkness of an area, which helps create a sense of dimension in the image
Common misconception
Rendering and sketching are the same process.
Sketching is like creating the blueprint or the structure of the 3D model. Rendering happens afterward and focuses on adding realistic appearances to the sketch, like making glass look transparent or wood look grainy.
Give the pupils materials to handle and sketch.
Teacher tip
Equipment
Pencil, pencil crayons, paper, material handling collection.
