c# - SharpDX draw multiple primitives at the same time -
i trying create high level api sharpdx. has able draw, stuck on how make work multiple draw calls @ same time.
this how call class
directxfinald d33d = new directxfinald(); here create new object of type viereck(rectangle)
viereck viereck = new viereck(0, 0, 0.2, 0.1, mybrush, mybrush, 1, false); here pass object class
d33d.drawdirectx(viereck); and works, problem is, want able can pass more objects @ given time, , let them drawn. tried update vertexbuffer , += vertices, problem different shapes need different topologies. here class:
namespace drawhost { public class directxfinald : drawhost.directxbased<d3d11>, idrawable { ; public directxfinald(idrawable objecttodraw = null, datastream stream = null) { this.objecttodraw = objecttodraw;

as can see you're calling attach ones. in attach method you're creating 1 vertex buffer, mesh depending on objecttodraw.
you should decouple shader compilation code , vertexbuffer setup.
you create class manage vertexbuffer , 'knows' how draw mesh.
for example: (pseudo)
[structlayout(layoutkind.sequential)] public struct vertex { public const int stride = 16 + 16; public vector4 pos; public color4 color; } public class mesh { private vertex[] _vertices; private int[] _indices; private sharpdx.direct3d11.buffer _indexbuffer; private sharpdx.direct3d11.buffer _vertexbuffer; private vertexbufferbinding _vertexbufferbinding; public mesh(vertex[] vertices, int[] indices) { // save vertices in field _vertices = value; var vbd = new bufferdescription( sharpdx.utilities.sizeof<vertex>() * _vertices.length, resourceusage.immutable, bindflags.vertexbuffer, cpuaccessflags.none, resourceoptionflags.none, 0); // setup vertex buffer _vertexbuffer = sharpdx.direct3d11.buffer.create<vertex>(dx11.device, _vertices, vbd); // create binding _vertexbufferbinding = new vertexbufferbinding(_vertexbuffer, vertex.stride, 0); _indices = value; var ibd = new bufferdescription( sizeof(int) * _indices.length, resourceusage.immutable, bindflags.indexbuffer, cpuaccessflags.none, resourceoptionflags.none, 0); // setup index buffer _indexbuffer = sharpdx.direct3d11.buffer.create<int>(dx11.device, _indices, ibd); } // selectbuffers select right vertex buffer. // combined draw method, rather not // should call ones when draw multiple same mesh. public void selectbuffers() { dx11.device.immediatecontext.inputassembler.setvertexbuffers(0, _vertexbufferbinding); dx11.device.immediatecontext.inputassembler.setindexbuffer(_indexbuffer, sharpdx.dxgi.format.r32_uint, 0); } public void draw() { dx11.device.immediatecontext.drawindexed(_indices.length, 0, 0); } } list<mesh> _meshes = new list<mesh>(); public void setupshaders() { vertexshaderbytecode = shaderbytecode.compilefromfile("minitri.fx", "vs", "vs_4_0", shaderflags.none, effectflags.none); vertexshader = new vertexshader(device, vertexshaderbytecode); pixelshaderbytecode = shaderbytecode.compilefromfile("minitri.fx", "ps", "ps_4_0", shaderflags.none, effectflags.none); ...... etc } public mesh setupmesh(object objecttodraw) { switch(.....) { // .. implement beautiful switch ;-) } return new mesh(vertices, indices); } public void init() { setupshaders(); _meshes.add(setupmesh(new dreieck(.....))); _meshes.add(setupmesh(new viereck(.....))); _meshes.add(setupmesh(new kreis(.....))); } public override void renderscene(draweventargs args) { renderer.device.immediatecontext.clearrendertargetview(renderer.rendertargetview, new color4(0.6f, 0, 0, 0)); foreach(var mesh in _meshes) { mesh.selectbuffers(); mesh.draw(); } return; } something that...
