This allows the selection to reach through entities to their corresponding ones on the underlying sketch which can be dragged if they are not fully constrained. This is decided in a new function Entity::CanBeDragged().
Create a new copy type for faces that includes the translation aspect of helical extrusions. Also swap the end remappings when the shell is inside out - this was also affecting some Revolve extrusions.
Allows distancing users from the internal "elem" member.
Add Get() and operator[].
Replace direct references to elem.
Make elem and elemsAllocated private in IdList/List.
Also, mark not just curves, but also points and normals derived from
construction requests as construction.
Also, don't always mark arc center point as construction just to
exclude it from chord tolerance bounding box calculation; instead,
special-case it there.
Before this commit, if any rendering mode except "show all occluded"
is enabled, points can be highlighted for corresponding to a DOF
after "Analyze → Degrees of Freedom" but then promptly occluded,
which is confusing.
Before this commit, when an entity is clicked at or dragged, and it
shares a place with other entities, which of them is selected is
decided more or less at random. This is particularly annoying when
dragging.
After this commit, when clicking, an entity from the current group
is given preference, and when dragging, an entity from a request
is given preference. This allows e.g. dragging points of a sketch
even when an extrusion of that sketch is active.
The states are:
* Draw all lines (on top of shaded mesh).
* Draw occluded (by shaded mesh) lines as stippled.
* Do not draw occluded (by shaded mesh) lines.
As usual, the export output follows the screen output.
This has several desirable consequences:
* It is now possible to port SolveSpace to a later version of
OpenGL, such as OpenGLES 2, so that it runs on platforms that
only have that OpenGL version;
* The majority of geometry is now rendered without references to
the camera in C++ code, so a renderer can now submit it to
the video card once and re-rasterize with a different projection
matrix every time the projection is changed, avoiding expensive
reuploads;
* The DOGD (draw or get distance) interface is now
a straightforward Canvas implementation;
* There are no more direct references to SS.GW.(projection)
in sketch rendering code, which allows rendering to multiple
viewports;
* There are no more unnecessary framebuffer flips on CPU on Cocoa
and GTK;
* The platform-dependent GL code is now confined to rendergl1.cpp.
* The Microsoft and Apple headers required by it that are prone to
identifier conflicts are no longer included globally;
* The rendergl1.cpp implementation can now be omitted from
compilation to run SolveSpace headless or with a different
OpenGL version.
Note these implementation details of Canvas:
* GetCamera currently always returns a reference to the field
`Camera camera;`. This is so that a future renderer that caches
geometry in the video memory can define it as asserting, which
would provide assurance against code that could accidentally
put something projection-dependent in the cache;
* Line and triangle rendering is specified through a level of
indirection, hStroke and hFill. This is so that a future renderer
that batches geometry could cheaply group identical styles.
* DrawPixmap and DrawVectorText accept a (o,u,v) and not a matrix.
This is so that a future renderer into an output format that
uses 2d transforms (e.g. SVG) could easily derive those.
Some additional internal changes were required to enable this:
* Pixmap is now always passed as std::shared_ptr<{const ,}Pixmap>.
This is so that the renderer could cache uploaded textures
between API calls, which requires it to capture a (weak)
reference.
* The PlatformPathEqual function was properly extracted into
platform-specific code. This is so that the <windows.h> header
could be included only where needed (in platform/w32* as well
as rendergl1.cpp).
* The SBsp{2,3}::DebugDraw functions were removed. They can be
rewritten using the Canvas API if they are ever needed.
While no visual changes were originally intended, some minor fixes
happened anyway:
* The "emphasis" yellow line from top-left corner is now correctly
rendered much wider.
* The marquee rectangle is now pixel grid aligned.
* The hidden entities now do not clobber the depth buffer, removing
some minor artifacts.
* The workplane "tab" now scales with the font used to render
the workplane name.
* The workplane name font is now taken from the normals style.
* Workplane and constraint line stipple is insignificantly
different. This is so that it can reuse the existing stipple
codepaths; rendering of workplanes and constraints predates
those.
Some debug functionality was added:
* In graphics window, an fps counter that becomes red when
rendering under 60fps is drawn.
This is to ensure that:
* it is clear, when looking at the point of usage, what is
the purpose of "true" or "false";
* when refactoring, a simple search will bring up any places that
need to be changed.
Also, argument names were synchronized between declaration and
implementation.
As an exception, these are not annotated:
* Printf(/*halfLine=*/), to avoid pointless churn.
Specifically, this enables -Wswitch=error on GCC/Clang and its MSVC
equivalent; the exact way it is handled varies slightly, but what
they all have in common is that in a switch statement over an
enumeration, any enumerand that is not explicitly (via case:) or
implicitly (via default:) handled in the switch triggers an error.
Moreover, we also change the switch statements in three ways:
* Switch statements that ought to be extended every time a new
enumerand is added (e.g. Entity::DrawOrGetDistance(), are changed
to explicitly list every single enumerand, and not have a
default: branch.
Note that the assertions are kept because it is legal for
a enumeration to have a value unlike any of its defined
enumerands, and we can e.g. read garbage from a file, or
an uninitialized variable. This requires some rearranging if
a default: branch is undesired.
* Switch statements that ought to only ever see a few select
enumerands, are changed to always assert in the default: branch.
* Switch statements that do something meaningful for a few
enumerands, and ignore everything else, are changed to do nothing
in a default: branch, under the assumption that changing them
every time an enumerand is added or removed would just result
in noise and catch no bugs.
This commit also removes the {Request,Entity,Constraint}::UNKNOWN and
Entity::DATUM_POINT enumerands, as those were just fancy names for
zeroes. They mess up switch exhaustiveness checks and most of the time
were not the best way to implement what they did anyway.
Specifically, take the old code that looks like this:
class Foo {
enum { X = 1, Y = 2 };
int kind;
}
... foo.kind = Foo::X; ...
and convert it to this:
class Foo {
enum class Kind : uint32_t { X = 1, Y = 2 };
Kind kind;
}
... foo.kind = Foo::Kind::X;
(In some cases the enumeration would not be in the class namespace,
such as when it is generally useful.)
The benefits are as follows:
* The type of the field gives a clear indication of intent, both
to humans and tools (such as binding generators).
* The compiler is able to automatically warn when a switch is not
exhaustive; but this is currently suppressed by the
default: ssassert(false, ...)
idiom.
* Integers and plain enums are weakly type checked: they implicitly
convert into each other. This can hide bugs where type conversion
is performed but not intended. Enum classes are strongly type
checked.
* Plain enums pollute parent namespaces; enum classes do not.
Almost every defined enum we have already has a kind of ad-hoc
namespacing via `NAMESPACE_`, which is now explicit.
* Plain enums do not have a well-defined ABI size, which is
important for bindings. Enum classes can have it, if specified.
We specify the base type for all enums as uint32_t, which is
a safe choice and allows us to not change the numeric values
of any variants.
This commit introduces absolutely no functional change to the code,
just renaming and change of types. It handles almost all cases,
except GraphicsWindow::pending.operation, which needs minor
functional change.
This will allow us in future to accept `const T &` anywhere it's
necessary to reduce the amount of copying.
This commit is quite conservative: it does not attempt very hard to
refactor code that performs incidental mutation. In particular
dogd and caches are not marked with the `mutable` keyword.
dogd will be eliminated later, opening up more opportunities to
add const qualifiers.
This commit also doesn't introduce any uses of the newly added const
qualifers. This will be done later.
This includes explanation and context for non-obvious cases and
shortens debug cycles when just-in-time debugging is not available
(like on Linux) by immediately printing description of the assert
as well as symbolized backtrace.
A previous attempt to fix this was done in 0128b8679. However, it was
not rigorous. The added offset was dependent on font size and it
introduced an error into edit control positioning. Further, it is
irrelevant to non-workplanes.
After this commit, the workplane drawing code adds a fixed offset
instead. Also, the "tab" is enlarged to not overlap with #XY etc.
Before this change, the two buttons "Show/hide shaded model" (S) and
"Show/hide hidden lines" (H) resulted in drawing the following
elements in the following styles:
Button | Non-occluded | Non-occluded | Occluded | Occluded
state | solid edges | entities | solid edges | entities
--------+--------------+--------------+-------------+--------------
!S !H | | | solid-edge | entity style
--------+ | +-------------+--------------
S !H | | | invisible
--------+ solid-edge | entity style +-------------+--------------
!S H | | | |
--------+ | | solid-edge | entity style
S H | | | |
--------+--------------+--------------+-------------+--------------
After this change, they are drawn as follows:
Button | Non-occluded | Non-occluded | Occluded | Occluded
state | solid edges | entities | solid edges | entities
--------+--------------+--------------+-------------+--------------
!S !H | | | solid-edge | entity style
--------+ | +-------------+--------------
S !H | | | invisible
--------+ solid-edge | entity style +-------------+--------------
!S H | | | |
--------+ | | hidden-edge | stippled¹
S H | | | |
--------+--------------+--------------+-------------+--------------
¹ entity style, but the stipple parameters taken from hidden-edge
In SolveSpace's true WYSIWYG tradition, the 2d view export follows
the rendered view exactly.
Also, it is now possible to edit the stipple parameters of built-in
styles, so that by changing the hidden-edge style to non-stippled
it is possible to regain the old behavior.
