Constructor & Destructor Documentation

◆ ON_PackedTextureRectangle()

ON_PackedTextureRectangle::ON_PackedTextureRectangle ( )

The default constructor sets all fields to zero.

Member Function Documentation

◆ UseEntireTexture()

void ON_PackedTextureRectangle::UseEntireTexture ( )

OUTPUT: Description: Sets the m_tex_* output fields to use the entire normalized texture. m_rotate = 0; m_tex_x0 = 0.0; m_tex_y0 = 0.0; m_tex_x1 = 1.0; m_tex_y1 = 1.0; m_tex_dx = 1.0; m_tex_dy = 1.0;

Member Data Documentation

◆ m_height

double ON_PackedTextureRectangle::m_height

rectangle height

◆ m_id

ON__INT_PTR ON_PackedTextureRectangle::m_id

for later identification

INPUT:

◆ m_next

class ON_PackedTextureRectangle* ON_PackedTextureRectangle::m_next

The default operator= and copy constructor work fine. Note that the m_next field is copied and you must adjust it as needed after making the copy. The input set of rectangles is managed as a linked list. Note that the default copy constructor and operator= copy the m_next value. If you make a copy, be sure to adjust the value m_next to something appropriate.

◆ m_tex_dx

double ON_PackedTextureRectangle::m_tex_dx

If you want to preserve the aspect of the input rectangle and have a uniform normalized texture coordinate scale for all the rectangles in the packing, limit yourself to using a normalized texture coordinate rectangle of size m_tex_dx by m_tex_dy inside the texture coordinate region specified by m_tex_x0,m_tex_y0 m_tex_x1,m_tex_y1. (m_tex_dx <= m_tex_x1 - m_tex_x0) (m_tex_dy <= m_tex_y1 - m_tex_y0)

◆ m_tex_dy

double ON_PackedTextureRectangle::m_tex_dy

◆ m_tex_rotated

char ON_PackedTextureRectangle::m_tex_rotated

tex_rotated will be set to 0 or 1 0 = not rotated The "width" direction of the rect corresponds to the "x" direction of the normalized texture coordinates and the "height" direction of the rect corresonds to the "y" direction of the normalized texture coordinates. 1 = rotated The "width" direction of the rect corresponds to the "y" direction of the normalized texture coordinates and the "height" direction of the rect corresonds to the "x" direction of the normalized texture coordinates.

◆ m_tex_x0

double ON_PackedTextureRectangle::m_tex_x0

The normalized texture coordinate region this rectangle can use has lower left corner at (m_tex_x0, m_tex_x1) and upper right corner at (m_tex_y0, m_tex_y1)

◆ m_tex_x1

double ON_PackedTextureRectangle::m_tex_x1

◆ m_tex_y0

double ON_PackedTextureRectangle::m_tex_y0

lower left normalized texture coordinate

◆ m_tex_y1

double ON_PackedTextureRectangle::m_tex_y1

upper right normalized texture coordinate

◆ m_width

double ON_PackedTextureRectangle::m_width

rectangle width

INPUT RECTANGLE: The input rectangle size is typically in world units, but can be in any unit system.
