struct mrpt::opengl::Texture::Options

Overview

Options while creating a texture from an image.

#include <mrpt/opengl/Texture.h>

struct Options
{
    // fields

    bool generateMipMaps = true;
    bool magnifyLinearFilter = true;
    bool enableTransparency = false;
    Wrapping wrappingModeS = Wrapping::Repeat;
    Wrapping wrappingModeT = Wrapping::Repeat;
    bool isColorData = true;
    const void* shareScope = nullptr;

    // construction

    Options();
};

Fields

bool magnifyLinearFilter = true

If set (true), interpolation will happen when getting closer to the texture (magnify).

Otherwise (false), it will be not interpolated, so each pixel will be rendered as a square box with constant color (e.g. suitable for gridmaps)

Wrapping wrappingModeS = Wrapping::Repeat

How to repeat texture coordinate “S”.

Wrapping wrappingModeT = Wrapping::Repeat

How to repeat texture coordinate “T”.

bool isColorData = true

If true (default), the texture is treated as sRGB color and auto-decoded to linear space by the GPU.

Set to false for data textures like normal maps.

const void* shareScope = nullptr

Textures assigned from the same image (same pixel buffer, alpha image and options) are uploaded once and shared, but only among those with the same non-null shareScope.

A scope must only be used with one OpenGL context, since texture names are not valid in other contexts (unless explicitly shared). nullptr (default): the texture is never shared. CompiledScene uses the EGL context it is compiled in, or one scope for all non-EGL contexts.
