Composition in Perspectives Elodie Fourquet Computational Aesthetics 2008
Motivation Goal: composition in a realistic image. Imaging versus modelling software. Renaissance art practices. 1935 Ford Woody by Jim Hatch Illustration. An engraving of Dürer. www.khulsey.com
Composition in Modelling Software Graphics Course T-shirt image done with Houdini. Modelling software interface.
Perspective in Imaging Software Kevin Husley Illustration Inc.: Empress of the Seas Cruise Ship Cutaway (Software: Adobe Creative Suite, Illustration Time: 960 hours).
Example of Artist Composition Scott More, illustrator, Coffee Stop. Painting Step-by-step. http://www.scottmooreart.com/
Traditional Composition Traditional artists prefer imaging over modelling software. Composition is hard and indirect in modelling software. Artists are working in image plane & depth simultaneously. Kevin Husley Illustration Inc. Metro Rail Project
Traditional Composition Traditional artists prefer imaging over modelling software. Composition is hard and indirect in modelling software. Artists are working in image plane & depth simultaneously. But, depth tools are absent in imaging software. Importance of construction lines. Kevin Husley Illustration Inc. Metro Rail Project

Renaissance Art Renaissance artists mastered perspective. Renaissance artists composed in the image plane. Elkins: from an unitary perspective to a pluralist approach. Kubovy: non-rectangular bodies with central projection. Kemp: more than ten constructions for perspective. An engraving of Dürer. Figure from Perspective Artistique, by Pierre Olmer 1948.
Renaissance: Image Composition The Baptism of Christ of Francesca, c. 1460. Composition according to Lavin.

Composition Framework Method to combine composition and perspective. Set a basic geometric pattern on the image plane.
Composition Framework Method to combine composition and perspective. Set a basic geometric pattern on the image plane. Build a tiled floor within the image plane pattern, which fixes depth & view parameters. Richard Talbot s images from Speculations on the Origins of Linear Perspective, 2003.

Compositional Grid: Square Subdivision
Definitions: VP, Horizon and Baseline VP H m.o m.o B VP H m.o B m.o
Floor: Transversal From Distance Point DP C DP B DP A f.t 0 f.t 5 f.p 5.. f.o 6.... f.p 1 f.p 0 f.o 2 f.o 1 f.o 0
Floor: Different Views Distance Point selection. Image Edge selection. DP on frame DP outside the frame DP close to VP
Walls: Setting Up The inscribed square is used for intermediate back wall. Lines from VP to intermediate wall corners are used. The room volume is completed from floor definition.
Walls: Different Views Distance Point location affects the volume shape. Cube looking volume. In-between volume Tunnel looking volume.
Blocks A block is a tile elevation. Fixed height across each floor horizontal. Recursive construction. For correct occlusion, ordering is needed.

Contribution: Framework Framework inspired by artistic practice of Renaissance. Composition in an image presenting depth is possible. Depth is not strictly defined, an image corresponds to multiple projections. Depth effect is produced by key relations. Floor works as an artistic composition device. 3D-like manipulation within compositional framework, by changing distance point and floor divisions. Paintings of Sandro Botticelli c.1480.
Future Work Increase flexibility: changing VP, horizon line position...
Future Work Increase flexibility: changing VP, horizon line position... Additional 3D-like manipulation and content: Rotation of blocks & of panels into depth. Tools for relative scale. Stimuli from panel rotation experiment. Paolo Ucello, Hunt by Night, c.1460.
