This diagram uses many of the concepts introduced in the first section of the Art Studio Chalkboard. This interior space was drawn using one-point perspective.
- The entire structure of this house interior is based on a simple square. By establishing the placement of the square it helps to set a foundation for the rest of the grid system. Once the horizonline and vanishing point is established.
- After establishing the square it can be used to define a floor grid that can be expanded to the walls and ceiling. The rear wall grid is created by simple verticals and horizontals because no perpective is necessary.
- The arched doorway in the right wall was created using a circle in perspective. The top half of the circle was created by subdividing a square.
When a grid system is carried into walls and ceiling areas it possible to systematically place objects in a space.
An example of a gridded floor that is done in this manner is Pieter Saendredam's Crossing the Nave of the St. Odulphusherk Assendelft. If you look at the architecture you will notice that it is constructed using one-point perspective.
