WebApr 8, 2024 · The projection matrix for each eye's view is used to ensure that the correct area of the scene is presented to each eye in order to create a believable 3D scene without introducing discomfort for the user. Examples Specifications Specification WebXR Device API # dom-xrview-projectionmatrix Browser compatibility By definition, a projection is idempotent (i.e. ). Every projection is an open map, meaning that it maps each open set in the domain to an open set in the subspace topology of the image. That is, for any vector and any ball (with positive radius) centered on , there exists a ball (with positive radius) centered on that is wholly contained in the image .

In statistics, the projection matrix $${\displaystyle (\mathbf {P} )}$$, sometimes also called the influence matrix or hat matrix $${\displaystyle (\mathbf {H} )}$$, maps the vector of response values (dependent variable values) to the vector of fitted values (or predicted values). It describes the influence each response … See more Suppose that we wish to estimate a linear model using linear least squares. The model can be written as $${\displaystyle \mathbf {y} =\mathbf {X} {\boldsymbol {\beta }}+{\boldsymbol {\varepsilon }},}$$ See more • Projection (linear algebra) • Studentized residuals • Effective degrees of freedom • Mean and predicted response See more The projection matrix has a number of useful algebraic properties. In the language of linear algebra, the projection matrix is the orthogonal projection onto the column space of the design matrix $${\displaystyle \mathbf {X} }$$.
