Detailed Description

+

Functions that generate common projection transformation matrices.

+

The matrices generated by this extension use standard OpenGL fixed-function conventions. For example, the lookAt function generates a transform from world space into the specific eye space that the projective matrix functions (perspective, ortho, etc) are designed to expect. The OpenGL compatibility specifications defines the particular layout of this eye space.

+

Include <glm/ext/matrix_projection.hpp> to use the features of this extension.

vec< 4, U, Q > const & viewport 
)
+
+ +

Define a picking region.

+
Parameters
+ + + + +
centerSpecify the center of a picking region in window coordinates.
deltaSpecify the width and height, respectively, of the picking region in window coordinates.
viewportRendering viewport
+
+
+
Template Parameters
+ + + +
TNative type used for the computation. Currently supported: half (not recommended), float or double.
UCurrently supported: Floating-point types and integer types.

GLM_FUNC_DECL vec<3, T, Q> glm::project (vec< 3, T, Q > const & obj,
mat< 4, 4, T, Q > const & model,
mat< 4, 4, T, Q > const & proj,
vec< 4, U, Q > const & viewport 
)
+
+ +

Map the specified object coordinates (obj.x, obj.y, obj.z) into window coordinates using default near and far clip planes definition.

+

To change default near and far clip planes definition use GLM_FORCE_DEPTH_ZERO_TO_ONE.

+
Parameters
+ + + + + +
objSpecify the object coordinates.
modelSpecifies the current modelview matrix
projSpecifies the current projection matrix
viewportSpecifies the current viewport
+
+
+
Returns
Return the computed window coordinates.
+
Template Parameters
+ + + +
TNative type used for the computation. Currently supported: half (not recommended), float or double.
UCurrently supported: Floating-point types and integer types.

mat< 4, 4, T, Q > const & model,
mat< 4, 4, T, Q > const & proj,
vec< 4, U, Q > const & viewport 
)
+
+ +

Map the specified object coordinates (obj.x, obj.y, obj.z) into window coordinates.

modelSpecifies the current modelview matrix
projSpecifies the current projection matrix
viewportSpecifies the current viewport
+
+
