Public Member Functions

TexTrans ()

TexTrans (uint texUnit)

Identity transform on texUnit = 0.

TexTrans (uint texUnit, const gutz::vec2f &bias, bool relBias=false)

Identity transform on 'texUnits'.

TexTrans (uint texUnit, const gutz::vec3f &bias, bool relBias=false)

TexTrans (uint texUnit, const gutz::mat4f &mat, bool relScale=false, bool relTrans=false)

TexTrans (uint texUnit, const gutz::vec3f &scale, const gutz::vec3f &bias, bool relScale, bool relBias)

uint texUnit () const

virtual gutz::arrayo2f operator() (const gutz::arrayw2f &rawTexCoords, const gutz::vec3f &primScale)

Apply transform to all coords specified in 'rawTexCoords' Divide scale and/or bias transform by 'primScale' if requested.

gutz::arrayo2f genTexCoords ()

Alternate interface.

gutz::arrayo2f genTexCoords (const gutz::arrayw2f coords, const gutz::vec3f &dimen)

virtual void setErrStream (std::ostream *os)

Where do you want gl errors to go? they must go somewhere, so don't set it to zero please.

virtual std::ostream * getErrStream () const

Where are gl errors going?

Protected Member Functions

void err (const char *where, const char *when=0) const

error

std::ostream & err () const

a simpler way, just use the stream! only for always print, this one automatically adds the objects name

void derr (const char *where, const char *when=0) const

debug error

bool glerr (const char *where, const char *when=0) const

gl error report only in debug mode, only if there is an error, if so return true

std::ostream & estr () const

this one just gives you the stream

Protected Attributes

std::ostream * m_err

) [virtual]

Apply transform to all coords specified in 'rawTexCoords' Divide scale and/or bias transform by 'primScale' if requested.
Note: There is a lot of type-casting and copying in this function b/c I am not using arrays-of-arrays. I am intentionally trading efficiency in this function for runtime, rendering efficiency by using a contiguous memory layout all for 2D ararys (vertex info).
