Detailed Description

Defines a material loaded from an .mtl file.

It uses QVector3D instead of Vec3f, etc, to be more compatible with Qt's OpenGL wrappers.

Definition at line 68 of file StelOBJ.hpp.

Member Enumeration Documentation

MTL Illumination models, see the developer doc for info.

Deprecated:
If possible, do not use. Illum use is very inconsistent between different modeling programs

Member Function Documentation

static QVector<Material> StelOBJ::Material::loadFromFile ( const QString &  filename)
static

Loads all materials contained in an .mtl file.

Does not check if the texture map files exist.

Returns
empty vector on error
static bool StelOBJ::Material::parseBool ( const QStringList &  params,
bool &  out 
)
staticprotected

Parses a bool from a parameter list (like included in the ::additionalParams) using the same logic StelOBJ uses internally.

Returns
true if successful, the output is written into out
static bool StelOBJ::Material::parseFloat ( const QStringList &  params,
float &  out 
)
staticprotected

Parses a float from a parameter list (like included in the ::additionalParams) using the same logic StelOBJ uses internally.

Returns
true if successful, the output is written into out
static bool StelOBJ::Material::parseVec2d ( const QStringList &  params,
Vec2d out 
)
staticprotected

Parses a Vec2d from a parameter list (like included in the ::additionalParams) using the same logic StelOBJ uses internally.

Returns
true if successful, the output is written into out

Member Data Documentation

ParamsMap StelOBJ::Material::additionalParams

Contains all other material parameters that are not recognized by this class, but can still be accessed by class users this way.

The key is the statement name (e.g. Ka, map_bump etc.), the value is the list of space-separated parameters to this statement

Definition at line 118 of file StelOBJ.hpp.

float StelOBJ::Material::d

Alpha value (1 means opaque).

-1 if not set by .mtl Note that both the d and Tr statements can change this value

Definition at line 97 of file StelOBJ.hpp.

QVector3D StelOBJ::Material::Ka

Ambient coefficient. Contains all -1 if not set by .mtl.

Definition at line 86 of file StelOBJ.hpp.

QVector3D StelOBJ::Material::Kd

Diffuse coefficient. Contains all -1 if not set by .mtl.

Definition at line 88 of file StelOBJ.hpp.

QVector3D StelOBJ::Material::Ke

Emissive coefficient. Contains all -1 if not set by .mtl.

Definition at line 92 of file StelOBJ.hpp.

QVector3D StelOBJ::Material::Ks

Specular coefficient. Contains all -1 if not set by .mtl.

Definition at line 90 of file StelOBJ.hpp.
