Intuitive Geometry “The abstractionist artists of yesterday are the tachists of today. Their historical content is analogous. the presence or absence of any geometrical contours do not count .

Form is no contour or casing, it is relationship.”— Waldemar Cordeiro Slide 1 Slide 1 (current slide) Slide 2 Slide 2 (current slide) Slide 3 Slide 3 (current slide) Slide 4 Slide 4 (current slide) Slide 5 Slide 5 (current slide) Slide 6 Slide 6 (current slide) Slide 7 Slide 7 (current slide) Slide 8 Slide 8 (current slide) Slide 9 Slide 9 (current slide) Opposition of position (space) Opposition of surface, duration (time) Opposition of direction (movement), theory of the element Opposition of chromatic groups (chromatic formation)Waldemar Cordeiro
