V3D_PROJ_TEST_CLIP_CONTENT	Clip the contents of the data being iterated over. Currently this is only used to edges when projecting into screen space. Clamp the edge within the viewport limits defined by V3D_PROJ_TEST_CLIP_WIN, V3D_PROJ_TEST_CLIP_NEAR & V3D_PROJ_TEST_CLIP_FAR. This resolves the problem of a visible edge having one of it's vertices behind the viewport. See: #32214. This is not default behavior as it may be important for the screen-space location of an edges vertex to represent that vertices location (instead of a location along the edge). Note Perspective views should enable V3D_PROJ_TEST_CLIP_WIN along with V3D_PROJ_TEST_CLIP_NEAR as the near-plane-clipped location of a point may become very large (even infinite) when projected into screen-space. Unless that point happens to coincide with the camera's point of view. Use V3D_PROJ_TEST_CLIP_CONTENT_DEFAULT instead of V3D_PROJ_TEST_CLIP_CONTENT, to avoid accidentally enabling near clipping without clipping by window bounds.

Exit 'local view' of given View3D editor, if it is active and there is nothing to display in it anymore.

Parameters

depsgraph	Optional, only required for #frame_selected.
frame_selected	Frame the newly out-of-local view to show currently visible selected objects. Will only do something if a valid depsgraph pointer is also provided.
smooth_viewtx	Smooth transition time (in milliseconds) between current view and final view, if changes are happening. Currently only used if #frame_selected is enabled.

◆ ED_view3d_calc_zfac_ex()

float ED_view3d_calc_zfac_ex	(	const RegionView3D *	rv3d,

Calculate a depth value from co, use with ED_view3d_win_to_delta.

Parameters

r_flip Set to zfac < 0.0 before the value is made signed. Since it's important in some cases to know if the value was flipped.

Returns: The unsigned depth component of co multiplied by rv3d->persmat matrix, with additional sanitation to ensure the result is never negative as this isn't useful for tool-code.

Clamp min/max by the viewport clipping.

Note: This is an approximation, with the limitation that the bounding box from the (mix, max) calculation might not have any geometry inside the clipped region. Performing a clipping test on each vertex would work well enough for most cases, although it's not perfect either as edges/faces may intersect the clipping without having any of their vertices inside it. A more accurate result would be quite involved.

Returns: True when the arguments were clamped.

Most of the time this isn't needed since you could assume the view matrix was set while drawing, however when functions like mesh_foreachScreenVert are called by selection tools, we can't be sure this object was the last.

for example, transparent objects are drawn after edit-mode and will cause the rv3d mat's to change and break selection.

'ED_view3d_init_mats_rv3d' should be called before view3d_project_short_clip and view3d_project_short_noclip in cases where these functions are not used during draw_object

◆ ED_view3d_offset_distance()

float ED_view3d_offset_distance	(	const float	mat[4][4],
		const float	ofs[3],
		float	fallback_dist )

This function solves the problem of having to switch between camera and non-camera views.

When viewing from the perspective of mat, and having the view center ofs, this calculates a distance from ofs to the matrix mat. Using fallback_dist when the distance would be too small.

Parameters

mat	A matrix use for the view-point (typically the camera objects matrix).
ofs	Orbit center (negated), matching RegionView3D.ofs, which is typically passed in.
fallback_dist	The distance to use if the object is too near or in front of ofs.

Returns: A newly calculated distance or the fallback.

For viewport operators that exit camera perspective.

Note: This differs from simply setting rv3d->persp = persp because it sets the ofs and dist values of the viewport so it matches the camera, otherwise switching out of camera view may jump to a different part of the scene.

		float	radius )

Return a new RegionView3D.dist value to fit the radius.

Note: Depth isn't taken into account, this will fit a flat plane exactly, but points towards the view (with a perspective projection), may be within the radius but outside the view. eg:

          +
pt --> + /^ radius
        / |
       /  |
view  +   +
       \  |
        \ |
         |
          +

Parameters

region	Can be NULL if use_aspect is false.
persp	Allow the caller to tell what kind of perspective to use (ortho/view/camera)
use_aspect	Increase the distance to account for non 1:1 view aspect.
radius	The radius will be fitted exactly, typically pre-scaled by a margin (VIEW3D_MARGIN).

◆ ED_view3d_viewcontext_init_object()

void ED_view3d_viewcontext_init_object	(	ViewContext *	vc,
		Object *	obact )

Re-initialize vc with obact as if it's active object (with some differences).

This is often used when operating on multiple objects in modes (edit, pose mode etc) where the vc is passed in as an argument which then references its object data.

Note: members ViewContext.obedit & ViewContext.em are only initialized if they're already set, by ED_view3d_viewcontext_init in most cases. This is necessary because the active object defines the current object-mode. When iterating over objects in object-mode it doesn't make sense to perform an edit-mode action on an object that happens to contain edit-mode data. In some cases these values are cleared allowing the owner of vc to explicitly disable edit-mode operation (to force object selection in edit-mode for e.g.). So object-mode specific values should remain cleared when initialized with another object.

void ED_view3d_win_to_delta	(	const ARegion *	region,

Calculate a 3D difference vector from 2D window offset.

Note: that ED_view3d_calc_zfac() must be called first to determine the depth used to calculate the delta.

When the zfac is calculated based on a world-space location directly under the cursor, the value of r_out can be subtracted from RegionView3D.ofs to pan the view with the contents following the cursor perfectly (without sliding).

Parameters

region	The region (used for the window width and height).
xy_delta	2D difference (in pixels) such as `event->mval[0] - other_x`.
zfac	The depth result typically calculated by ED_view3d_calc_zfac (see its doc-string for details).
r_out	The resulting world-space delta.

◆ ED_view3d_win_to_origin()

void ED_view3d_win_to_origin	(	const ARegion *	region,

Calculate a 3D origin from 2D window coordinates.

Note: Orthographic views have a less obvious origin, Since far clip can be a very large value resulting in numeric precision issues, the origin in this case is close to zero coordinate.

Parameters

region	The region (used for the window width and height).
mval	The area relative 2D location (such as `event->mval` converted to float).
r_out	The resulting normalized world-space direction vector.

v3d	The 3D viewport (used for near clipping value).
mval	The area relative 2D location (such as event->mval, converted into float[2]).

Calculate a 3D viewpoint and direction vector from 2D window coordinates. This ray_start is located at the viewpoint, ray_normal is the direction towards mval. ray_start is clipped by the view near limit so points in front of it are always in view. In orthographic view the resulting ray_normal will match the view vector. This version also returns the ray_co point of the ray on window plane, useful to fix precision issues especially with orthographic view, where default ray_start is set rather far away.

Parameters

v3d	The 3D viewport (used for near clipping value).
mval	The area relative 2D location (such as `event->mval`, converted into float[2]).
do_clip_planes	Optionally clip the start of the ray by the view clipping planes.

Calculate a 3D segment from 2D window coordinates. This ray_start is located at the viewpoint, ray_end is a far point. ray_start and ray_end are clipped by the view near and far limits so points along this line are always in view. In orthographic view all resulting segments will be parallel.

Calculate a 3D direction vector from 2D window coordinates. The resulting direction points away from the view-point, making the result useful to perform ray-casts into a 3D scene. In orthographic view all input coordinates result in the same vector.

Note: doesn't rely on ED_view3d_calc_zfac for perspective view, get the vector direction to the mouse cursor as a normalized vector.

Parameters
