For an image synthesis must add objects, lights and cameras to the scene. The representation of these objects depend on the scene illumination, the camera parameters and the visual properties of these objects that basically know as your “color” or “material”. We can say that the appearance of an object… (leer más)
The study of the disciplines of classical geometry can be reinforced by using tools that allow constructions that can be changed dynamically: variational constructions.
The tool “Geogebra” It will serve to illustrate these concepts and demonstrate the importance of detailed knowledge of geometric relationships to ensure the robustness of the buildings we use in geometric reasoning, as, sometimes, some constructions may lose their validity.
a conical (punctual) It is the locus of the points of intersection of two projective beams.
This model has been verified with a variational model of projective shaft made with Geogebra.
By studying the true magnitude of a line we saw that we could turn calculate the angle of this line with respect to a projection plane, namely, its slope.
In a plane we can determine endless lines with different direction contained therein. One of these lines form the maximum angular condition with respect to the projection plane.
Projective geometry constructions made with tools to analyze their invariants are very useful for the study of this discipline of Graphic Expression. We will see one of these constructions made with the software “GeoGebra”, in particular for determining the projective axis of two projective series.
A representation of a simple object can not be easily solved in all cases. Some of these exercises are useful in an early stage of formation of our students, as they show the difficulty of unequivocally represent objects whose spatial restitution is accurate.
I set out to solve a problem with a curious piece of technical drawing that was determined by two of its projections.
We have seen in studying the concept of power or theorems Hick and height metric relations between segments.
In these relationships, along with the Pythagorean Theorem segments are related by quadratic forms that can also be interpreted as areas (product of two lengths)
The Serie “Caminandes” made with animation suite “Blender” It presents its third episode entitled “Llamigos”.
Hand of its director Pablo Vazquez, Koro flame in Patagonia faces a new adventure, as usual, eat something tasty.
The study of conic can be made from different geometric approaches. One of the most used is the analysis that determined from planar sections in a cone of revolution.
From this definition it is possible to infer metric properties of these curves, plus new definitions of the same.
