class mrpt::opengl::CText¶

A 2D text (bitmap rendering): it always “faces the observer” despite it’s at some 3D location.

Use setString and setFont to change the text displayed by this object.

All texts appear with the font GLUT_BITMAP_TIMES_ROMAN_10 for now (i.e. setFont is ignored)

Construction¶

CText(const std::string& str = std::string(""))

Constructor.

Methods¶

void setString(const std::string& s)

Sets the text to display.

std::string getString() const

Return the current text associated to this label.

void setFont(const std::string& s, int height)

Sets the font (It has no effect yet!)

virtual shader_list_t requiredShaders() const

Returns the ID of the OpenGL shader program required to render this class.
