21 ### Filling TBuffer3D and Adding to Viewer
22 
23 The viewers behind the TVirtualViewer3D interface differ greatly in their
24 capabilities e.g.
25 
26  - Some know how to draw certain shapes natively (e.g. spheres/tubes in OpenGL)
27  - others always require a raw tessellation description of points/lines/segments.
28  - Some need the 3D object positions in the global frame, others can cope with
29  local frames + a translation matrix - which can give considerable performance
30  benefits.
31 
32 To cope with these situations the object buffer is filled out in negotiation
33 with the viewer. TBuffer3D classes are conceptually divided into enumerated
34 sections Core, BoundingBox, Raw etc (see TBuffer3D.h for more details).
35 
36 \image html base_tbuffer3d.png
37 
38 The `SectionsValid() / SetSectionsValid / ClearSectionsValid()` methods of
39 TBuffer3D are used to test/set/clear these section valid flags.
40 
41 The sections found in TBuffer3D (`Core/BoundingBox/Raw Sizes/Raw`) are sufficient
42 to describe any tessellated shape in a generic fashion. An additional
43 `ShapeSpecific` section in derived shape specific classes allows a more abstract
44 shape description ("a sphere of inner radius x, outer radius y"). This
45 enables a viewer which knows how to draw (tessellate) the shape itself to do so,
46 which can bring considerable performance and quality benefits, while providing a
47 generic fallback suitable for all viewers.
48 
49 The rules for client negotiation with the viewer are:
50 
51  - If suitable specialized TBuffer3D class exists, use it, otherwise use TBuffer3D.
52  - Complete the mandatory Core section.
53  - Complete the ShapeSpecific section if applicable.
54  - Complete the BoundingBox if you can.
55  - Pass this buffer to the viewer using one of the AddObject() methods - see below.
56 
57 If the viewer requires more sections to be completed (Raw/RawSizes) AddObject()
58 will return flags indicating which ones, otherwise it returns kNone. You must
59 fill the buffer and mark these sections valid, and pass the buffer again. A
60 typical code snippet would be:
61 
62 ~~~ {.cpp}
63 TBuffer3DSphere sphereBuffer;
64 // Fill out kCore...
65 // Fill out kBoundingBox...
66 // Fill out kShapeSpecific for TBuffer3DSphere
67 // Try first add to viewer
68 Int_t reqSections = viewer->AddObject(buffer);
69 if (reqSections != TBuffer3D::kNone) {
70  if (reqSections & TBuffer3D::kRawSizes) {
71  // Fill out kRawSizes...
72  }
73  if (reqSections & TBuffer3D::kRaw) {
74  // Fill out kRaw...
75  }
76  // Add second time to viewer - ignore return cannot do more
77  viewer->AddObject(buffer);
78  }
79 }
80 ~~~
81 
82 `ShapeSpecific`: If the viewer can directly display the buffer without
83 filling of the kRaw/kRawSizes section it will not need to request client side
84 tessellation.
85 
86 Currently we provide the following various shape specific classes, which the
87 OpenGL viewer can take advantage of (see TBuffer3D.h and TBuffer3DTypes.h)
88 
89  - TBuffer3DSphere - solid, hollow and cut spheres*
90  - TBuffer3DTubeSeg - angle tube segment
91  - TBuffer3DCutTube - angle tube segment with plane cut ends.
92 
93 
94 *OpenGL only supports solid spheres at present - cut/hollow ones will be
95 requested tessellated.
96 
97 Anyone is free to add new TBuffer3D classes, but it should be clear that the
98 viewers require updating to be able to take advantage of them. The number of
99 native shapes in OpenGL will be expanded over time.
100 
101 `BoundingBox:` You are not obliged to complete this, as any viewer
102 requiring one internally (OpenGL) will build one for you if you do not provide.
103 However to do this the viewer will force you to provide the raw tessellation, and the
104 resulting box will be axis aligned with the overall scene, which is non-ideal
105 for rotated shapes.
106 
107 As we need to support orientated (rotated) bounding boxes, TBuffer3D requires
108 the 6 vertices of the box. We also provide a convenience function, SetAABoundingBox(),
109 for simpler case of setting an axis aligned bounding box.
110 
111 ### Master/Local Reference Frames
112 
113 The `Core` section of TBuffer3D contains two members relating to reference
114 frames:
115 `fLocalFrame` & `fLocalMaster`. `fLocalFrame` indicates if any positions in the
116 buffer (bounding box and tessellation vertexes) are in local or master (world frame).
117 `fLocalMaster` is a standard 4x4 translation matrix (OpenGL column major ordering)
118 for placing the object into the 3D master frame.
119 
120 If `fLocalFrame` is kFALSE, `fLocalMaster` should contain an identity matrix. This
121 is set by default, and can be reset using `SetLocalMasterIdentity()` function.
122 
123 Logical & Physical Objects.
124 There are two cases of object addition:
125 
126  - Add this object as a single independent entity in the world reference frame.
127  - Add a physical placement (copy) of this logical object (described in local
128  reference frame).
129 
130 The second case is very typical in geometry packages, GEANT4, where we have
131 very large number repeated placements of relatively few logical (unique) shapes.
132 Some viewers (OpenGL only at present) are able to take advantage of this by
133 identifying unique logical shapes from the `fID` logical ID member of
134 TBuffer3D. If repeated addition of the same `fID` is found, the shape
135 is cached already - and the costly tessellation does not need to be sent again.
136 The viewer can also perform internal GL specific caching with considerable
137 performance gains in these cases.
138 
139 For this to work correctly the logical object in must be described in TBuffer3D
140 in the local reference frame, complete with the local/master translation. The
141 viewer indicates this through the interface method
142 
143 ~~~ {.cpp}
144 PreferLocalFrame()
145 ~~~
146 
147 If this returns kTRUE you can make repeated calls to AddObject(), with TBuffer3D
148 containing the same fID, and different `fLocalMaster` placements.
149 
150 For viewers supporting logical/physical objects, the TBuffer3D content refers
151 to the properties of logical object, with the `fLocalMaster` transform and the
152 `fColor` and `fTransparency` attributes, which can be varied for each physical
153 object.
154 
155 As a minimum requirement all clients must be capable of filling the raw tessellation
156 of the object buffer, in the master reference frame. Conversely viewers must
157 always be capable of displaying the object described by this buffer.
158 
159 ### Scene Rebuilds
160 
161 It should be understood that AddObject is not an explicit command to the viewer
162  - it may for various reasons decide to ignore it:
163 
164  - It already has the object internally cached .
165  - The object falls outside some 'interest' limits of the viewer camera.
166  - The object is too small to be worth drawing.
167 
168 In all these cases AddObject() returns kNone, as it does for successful addition,
169 simply indicating it does not require you to provide further information about
170 this object. You should not try to make any assumptions about what the viewer
171 did with it.
172 
173 This enables the viewer to be connected to a client which sends potentially
174 millions of objects, and only accept those that are of interest at a certain
175 time, caching the relatively small number of CPU/memory costly logical shapes,
176 and retaining/discarding the physical placements as required. The viewer may
177 decide to force the client to rebuild (republish) the scene (via
178 a TPad repaint at present), and thus collect these objects if the
179 internal viewer state changes. It does this presently by forcing a repaint
180 on the attached TPad object - hence the reason for putting all publishing to
181 the viewer in the attached pad objects Paint() method. We will likely remove
182 this requirement in the future, indicating the rebuild request via a normal
183 ROOT signal, which the client can detect.
184 
185 ### Physical IDs
186 
187 TVirtualViewer3D provides for two methods of object addition:virtual Int_t AddObject(const
188 TBuffer3D & buffer, Bool_t * addChildren = 0)
189 
190 ~~~ {.cpp}
191 virtual Int_t AddObject(UInt_t physicalID, const TBuffer3D & buffer, Bool_t * addChildren = 0)
192 ~~~
193 
194 If you use the first (simple) case a viewer using logical/physical pairs
195 SetSectionsValid(TBuffer3D::kBoundingBox); will generate IDs for each physical
196 object internally. In the second you can specify a unique identifier from the
197 client, which allows the viewer to be more efficient. It can now cache both logical
198 and physical objects, and only discard physical objects no longer of interest as
199 part of scene rebuilds.
200 
201 ### Child Objects
202 
203 In many geometries there is a rigid containment hierarchy, and so if the viewer
204 is not interested in a certain object due to limits/size then it will also
205 not be interest in any of the contained branch of descendents. Both AddObject()
206 methods have an addChildren parameter. The viewer will complete this (if passed)
207 indicating if children (contained within the one just sent) are worth adding.
208 
209 ### Recycling TBuffer3D
210 
211 Once add AddObject() has been called, the contents are copied to the viewer
212 internally. You are free to destroy this object, or recycle it for the next
213 object if suitable.
