inline

If CTRL is expected we need to look at keysym instead. Because CTRL changes the output of the key press to something unexpected we need to check against the key press action instead.

keysym is always lowercase

Compare to zero to avoid performance warnings. Did we find the modifiers we're looking for (modifierMask) in the modifiers currently pressed (kev->modifiers)? OR Are we not looking for any modifiers AND none of the modifiers are currently pressed? (ignoring the lock state and mouse button modifiers)

	)

Finds the point that (1) lies along the plane passing through p3 and perpendicular to the vector p1-p2 and (2) lies along the line defined by p1 and p2

Method: We have 3 unknowns (x,y,z) and 3 equations: The first known equation is the equation of the plane where vA is the vector p2 - p1 eq 1: (x - p3.x)vA.x + (y - p3.y)vA.y + (z - p3.z)vA.z = 0 The second and third equations are the projection form of the line defined by the points p1 and p2. eq 2: (x - p1.x) / (p2.x - p1.x) = (y - p1.y) / (p2.y - p1.y) eq 3: (x - p1.x) / (p2.x - p1.x) = (z - p1.z) / (p2.z - p1.z)

Parameters

p1	First point in the vector
p2	Second point in the vector
p3	A point in the plane p1,p2,p3

Returns: The point of intersection

void disti::SetNPOTState ( ImageNPOTMode state )

Enable/Disable global Non Power Of Two capability. This will override the texture's setting from the editor.

Note: NPOT detection is not currently supported. (GLS-5940)

Parameters

state The state to set it to. Will enable, disable, or apply auto detection for if NPOT support is available.

void disti::SetReleaseImageDataDefault ( bool enable )

By default, Image instances release their texture data in main memory after loading it to the GPU. This flag controls that default behavior for new Image instances. Set to false if you want all Images to keep a copy of their texture data loaded in main memory. (Note: This can dramatically increase memory usage.)

Note: The default applies only to Image instances created after this flag is set. To set or get the value behavior for a particular Image instance, call Image::SetReleaseImageDataEnabled() or Image::IsReleaseImageDataEnabled(), respectively.; Default value: true

Parameters

enable The new default value
