332888f3b5 Switch mem allocation to custom memory block
No longer repeatedly invoke malloc for retrieving memory. Some operations still
leak memory (notably audio streaming). We introduce notion of Transient and
Permanent storage. Transient memory is used for data in memory that is
temporarily allocated (i.e. graphics for that frame's output), and permanent as
more like game state storage.

We now give out pointers from a pre-allocated block of memory, so we have no
allocation cost and benefits of reduced memory leaks. The transient block gets
reset every frame. Any memory allocated within is cleared at no cost simply by
rearranging the base pointer of the memory block.

85b757aaa7 Update debug display for render groups 2016-09-23 21:15:22 +10:00
82421ca64c Improve performance by swapping render groups
Last used render groups are brought to front of render list when searching for
valid group- as per- recently used items are likely to be used again.

3894d33485 Fix rotation on render, change rendering code
Premultiply transformation matrix onto vertices before sending onto GPU to
preserve transformation properties of entities before being batched into
a general group. This removes the model matrix from the shader pipeline- instead
in rendering code we deal in world space (which works out to be more intuitive).
Only in the last step in GLSL we convert back to normalised coordinates.

88ce511f2b Entity rendering now uses rectangle rendering code 2016-09-22 19:00:44 +10:00
23720fae19 Fix batch-render of strings, fix group logic
Incorrect assumption that strings only needed degenerate vertexes at the start
and end of each string instead of characters causing render "wings" between
separate strings.

Fix render-group not switching to next group if current group is full.

ebe09bd345 Improved render groups, use degenerate triangles
Degenerate triangles allows a single triangle strip call to be called on
multiple independent triangles without "connecting" strips inbetween the
triangles.

ec7a9e41ff Begin draft imeplementation of batched rendering
Render all entities with the same texture in one call. Currently only
implemented for humanoid entities. Since we are rendering using triangle strips,
between entities there is invalid rastered data between entities. Using
degenerate triangles this may be mitigated, by indicating to OGL which triangles
it can skip in the rendering process.

7cb13b3cf8 Add additional entity struct data
Attempting to add child weapon data to an entity has revealed the need for an
entity origin to which children start transformations from. Worth exploring
scene graphs in the future.

5c4f493979 Add support for more attack-animations
Exploratory code to determine how to architect the engine for increasing
requirements in game play.

and extraneous computations in the function has been moved to the
appropriate locations.
