Hello, I have a simple question,
what is the equivalent to Gizmos.DrawWireCube or in general how can I only draw a generic wire shape such as circle and cube for example?
I'm glad you like my stuff <3
as for including wire shapes - this is unfortunately quite a lot of work, and opens up a whole can of worms of things I'd now have to add, not only for the existing shapes, but for any additional shapes I add,
not to mention, they wouldn't be able to deal with transparency as well as other shapes, since they are composite shapes
Works like a charm, thank you, for the reply and this awesome library.
I've been a long-time follower of you, and your math/shaders videos have helped me a lot during the years, so thank you once again.
Ps: I think you should include wire shapes in the API, I am sure I am not the only one that would love to have this feature out of the box.
there are no built-in meta-shapes like this, so you'd have to write your own based on what needs you have
Drawing a wire cube for instance is a matter of iterating through all the pairs of points making up the edges of a cube and drawing a line:
// Draws a wireframe cube using Draw.Line
static void DrawWireCube( Vector3 position, Quaternion rotation, Vector3 scale ) {
using( Draw.MatrixScope ) {
Draw.Matrix *= Matrix4x4.TRS( position, rotation, scale );
foreach( ( Vector3 a, Vector3 b ) in cubeEdges )
Draw.Line( a, b, LineEndCap.Round );
}
}
// an array of all vertex pairs of a cube's edges
static readonly (Vector3 a, Vector3 b)[] cubeEdges = GetCubeEdges().ToArray();
// generates all vertex pairs of cube edges
static IEnumerable<(Vector3, Vector3)> GetCubeEdges() {
Vector3 Scoot( Vector3 v, int n ) => new Vector3( v[n], v[( n + 1 ) % 3], v[( n + 2 ) % 3] );
for( int a = 0; a < 3; a++ )
for( int ix = -1; ix < 2; ix += 2 )
for( int iy = -1; iy < 2; iy += 2 )
yield return (
Scoot( new Vector3( -1, ix, iy ), a ),
Scoot( new Vector3( 1, ix, iy ), a )
);
}
