  • the formulas are simple to calculate, such as being linear, so the three-dimensional images can be generated quickly.
  • the formulas are also interrelated so that changing the parameters of one formula results in changes in the parameters of other formulas.
  • parameter changes can be determined by using a conventional matrix type solving method. And particularly, wherein the parameters are limited to either a value of zero or one for simplicity in solving the matrix.
  • each polygonal or mesh model consists of a number of vertices that define the form of the model.
  • each mesh model has a number of vertices wherein the coordinates of these vertices depend on a plurality of parameters values.
  • v is a vector which begins at point (0,0,0) , and ends at (x ⁇ ,yt,Zi) ,

  • x t J are vector constant.
  • Formula 362 is desired because it is a simple linear function that can be calculated quickly.
  • Formula 362 also has a minimal number of variables that must be stored with vertices for a parameterized three- dimensional model. In particular, for each vertex, the value of n vector constants is stored, where n is a number of parameters.

  • This step includes a calibration process wherein the constants in the morphing formula are calculated. For instance, if formula 364 is used for the morphing formula, then the values of constants x t J should be determined for each vertex.

  • v ; . is the i-th vertex of the k-th variant of the three-dimensional model
  • formula 362 for defining the morphing properties imposes several restrictions when used within the above described application of multi-parametric morphing for parameterization of a three-dimensional human body model.
  • Formula 362 is suitable for parameters that, in part, are independent. That is, formula 362 is suitable if some parameters such as bust size, hip size, and height can be treated as independent.
  • bust size does not affect vertices that belong to the hips
  • size of the hips does not affect the vertices belonging to the bust
  • changing the height affects only the vertical coordinate of the vertices. Accordingly, while not fully correct for human body, formula 362 is appropriate for general three-dimensional simulation of the human body.
  • Formula 374 can be used for defining the morphing properties in formula 360, whereby the full formula for vertices becomes:
  • Formula 376 requires more calibration three-dimensional models than formula 364. Moreover, formula 376 has more constants than formula 364, so the size of additional data for each vertex is increased. However, formula 376 provides more powerful parameterization of three-dimensional models because dependent parameters are used.

  • An approach to gain this effect consists of designing the clothing model in this way that it fits the basic model of the avatar and applies the exactly same parameterization as the avatar model. This can be accomplished by creation of calibration models for clothing that are similar to the avatar model. However, this is not convenient since it requires the creation of a lot of models for each article of clothing to be displayed.
  • a preferred method to overcome the above problem is calibration of three- dimensional models using an already parameterized model referred to herein as a template model.

  • Avatar models can be used as template models for types of clothing that fit closely to the body such as various pants, short skirts, shirts, and the like. However, other types of loose fitting clothing such as dresses and coats should have models created for them without the use of a template. Once these models for loose fitting clothing are created, they can be used as templates to create additional models.

Abstract

L'invention concerne un système et un procédé permettant de produire des représentations graphiques de valeurs, biens et services proposés à la vente et/ou à la location. Ce système peut comporter un serveur d'affichage connecté de manière à fonctionner, via un serveur marchand, au navigateur d'un client. Le serveur d'affichage fournit différentes vues d'un modèle graphique qui est généré suite à la saisie de données émises par un utilisateur se servant du navigateur. Le serveur d'affichage permet également aux produits ou aux services vendus par le serveur marchand d'être disposés, sur la base d'un modèle graphique de l'utilisateur, en vue de donner une image composite du modèle graphique ainsi que des produits ou services proposés.
